According to any statistics what state of health normaly people are diagnosed with cancer?
does anyone know are normaly people's health is compromised already or it just happens even when people are at the best shape and form and healthy.
According to any statistics what state of health normaly people are diagnosed with cancer?
Although I do not know the exact statistics you are asking for part of my job is to report the information cancer statistics are based on. There are known risk factors to most types of cancer and some do compromise ones health, but this does not mean a person with these risk factors will ever get cancer it only helps doctors to be more aware of the possibility. Cancer can strike anyone, of any age with or without any other medical conditions.
What we do know, is when cancer is found during a routine screening exam or by accident while treating something else, in a patient with no symptoms the cancer is most likely found in an early stage and their prognosis is much better regardless of pre-existing medical conditions.
Aging is a major risk factor in the most common types of cancer and since our health tends to become compromised in some way as we age it may appear compromised health may play a part, but from what we know it is only a very small part, if any.
We also know that when someone in their 20s or 30s is diagnosed with one of these common types of cancer, such as lung, breast, colon, there is rarely any pre-existing medical conditions involved, yet their prognosis is very poor and often do not survive.
When children have cancer they are almost always otherwise normal healthy kids.
There are many types of cancer and they have their own unique behaviors and risk factors making it impossible to compare one type to another. However, overall a person whose health has been compromised in some way is not a determining factor.
Reply:i dont know the statistics but i felt better than i had for years i had lost 15st and was feeling great about life and was suddenly diagnosed with throat cancer.the amount of people having chemo shocked me and i did not realise how many peoples lives were touched by cancer it was scary.but the oncology nurse put it all intp perpective she told me the reason they were seeing so many people with cancer was because they were curing most of them nowadays.
Reply:I've known a few of people that got diagnosed with cancer. They seemed like their regular self, no signs or anthing out of the usual. Til they went for their regular chkup, then they found out. I strongly recommend regular check-ups, especially if your family has a history of a certain disease or heredity problems. Cancer is a terrible disease, and I wish no one ever gets it, or ever has to go through it.
Reply:My son was 17 and a healthy high school athlete. He was in excellent physical condition as he was playing basketball at the time. He had brutal basketball practices and he worked full time on weekends, besides going to school. He used to come home from practices and tell me how he could not keep up with the other boys . . I just told him to keep on trying and never suspected a thing. He had just had a sports physical and his doctor told us he was very healthy . .the physical was at the end of December and by the first of March he was diagnosed with stage IV abdominal sarcoma. He was filled with cancer . . one tumor was the size of a volley ball . . . one week he was a healthy teen playing basketball and the next week he had life threatening advanced cancer. No warning.
Ironically, I believe that the fact he was so healthy when they found the cancer . .actually prolonged his life and allowed him to fight for the past three years with great quality of life as well. So it appears that cancer does not discriminate . . anyone healthy or unhealthy can get cancer at any age . . but if you are healthy to begin with you have a better chance at fighting the cancer.
Unfortunately, my son did not survive. But he was always considered healthy for a cancer patient, recovered from surgeries quickly, tolerated high dose chemo, and had few to no lasting side effects.
Reply:Cancer affects the healthy and unhealthy alike.
Myself, I had been a vegan for several years, had never smoked, exercised regularly, had a healthy, largely organic diet full of fruit and veg, was a juicing fiend, and had every reason to feel optimistic and positive when I was diagnosed.

What are the statistics to back up the "Every 15 Minutes" claims?
A teenager is killed, on average, once every 15 minutes? That's 96 teens killed, on average, in a car accident every day!
What are the statistics to back up the "Every 15 Minutes" claims?
Go to the NTSB for more current information.
t is estimated that 16-year-olds are 3 times more likely to die in a motor vehicle crash than the average of all drivers. 16 year-olds have higher crash rates than drivers of any other age.
Motor Vehicle Crashes are the leading cause of death for teenagers.
3,571 16-20-year-old drivers died in auto accidents in 2003, down 4.1% from 3,723 in 2002, according to the National Highway Traffic Safety Administration (NHTSA).
$40.8 billion was the estimated economic impact of auto accidents involving 15-20 year old drivers in 2002 (NHTSA).
Inexperience behind the wheel is the leading cause of teenage crashes.
In 2001, two thirds of teens killed in auto accidents were not wearing seat belts.

Okay, let's play pure stats. %26amp; logical conclusions. All convicted murderers on death row have eaten mashed potatoes %26amp; gravy, so, if you eat mashed potatoes %26amp; gravy, you'll become a murderer. See the fallacy? The people that made "Reefer Madness" didn't. Stats can be bent to whatever direction you want them to go. Not good science ; that has controls.
Facts that stand the test of time are better "stats". Like that over the past 20 yrs. or so, 38% of traffic fatalities involve alcohol, 6 % of which are drunks that were pedestrians at the time ( walked off curb in front of moving vehicle.)
That means that 68% of traffic fatalities are caused by sober people that JUST DON'T KNOW HOW TO DRIVE!

What are the STATISTICS of HIV contraction through the eye via sperm from a facial? ( only a lil in the eye)?
I asked a similiar question a few days back and got some good answers, I understand anything is probable but what are the statistics? Does anyone know or can shed a hypthesis? I think I'm worrying about nothing, but these days you cannot be too careful. I dont know why this is bothering me so much...lol...sorry.
What are the STATISTICS of HIV contraction through the eye via sperm from a facial? ( only a lil in the eye)?
I could find no statistics involving what you are asking. Since the eye is a mucus membrane, in theory, HIV transmission is possible but I could find no such confirmed incidents.
I suggest that in the future, you abstain from "facials" with semen.

Reply:I found it mentioned as possible, but no statistics. With HIV, I think even negligible risk is not worth taking.

Is math statistics or intermediate algebra an easier college class?
I need to take one of these classes for college but I'm not the greatest at math. Which is easiest?
Is math statistics or intermediate algebra an easier college class?
Depends. Statistics generally doesn't require prior knowledge of math. It is generally regarded as a more difficult subject compared to int. algebra. If your not good at math, take stats though. Its just basically memorizing bunch of formulas and plugging em into equations. You don't need to know any math going into class, and you realy wont remember anything you've learned the instant the semester is over. If your not required to take anymore math, just stick to stats.

What's the difference between Maths Mechanic and statistics?
In detail if you can please
What's the difference between Maths Mechanic and statistics?
maths mechanics deals with engineering aspects of mathematics. calculations of speed, mass, distance, angles of projectory, strenght etc and thats the basic stuff
Statistical maths is the study of numbers on a scientific approach that benefits insurance businesses, investments, research estbaklishments, etc. examples of statistical maths is anaylsying trends and patterns, probililties etc.
Reply:Mechanics is a branch of physics (mathematically) and involves forces etc.
Statistics is working with numbers and involves playing with figures and probabilities etc.
I would go into detail but there really isn't any point; you can easily find out more information through search engines such as Google, or look into Wikipedia online for some in-depth data.
P.S : If your thinking of studying either of these, I would recommend mechanics if you are interested in physics, but it is considered to be a lot harder than statistics. However, having said that, many find statistics tedious due to collecting and representing data in endless ways.

Is there a site where I can get statistics on flight over-bookings?
Some relatives of mine recently had their vacation spoilt by being "bumped off" their flights on both the outward and return legs.This was in spite of having checked in early and having boarding cards in their possession. Evidence is that the airline knew that they were overfilled eight hours before the departure time, so they re-routed a group of ten passengers, causing them to lose a day of their vacation. The same thing happened on the way back! Ironically, all the people had paid a surcharge to use that particular airline. Is there any site which gives information on the average overbooking by the various airlines? I have looked at dozens of sites and found nothing useful yet, using normal searches. Have we an insider out there who can point me in the right direction?
Is there a site where I can get statistics on flight over-bookings?
Have you tried www.DOT.gov? The number of tickets sold on a particular flight kinda goes by the "no show" factor of the flights in the previous years around that time of year. For example, if an average of 10 customers tend not to show up for their flights in previous years, that flight may be oversold by 10 this time around, and thats when EVERYONE shows up. Your relatives are definitely entitled to compensation if they were involuntarily denied boarding on the flight they booked. ***unless they bought a really cheap ticket through a cheap travel agency (priceline to name one). sometimes you are not entitled to oversale rights with those tickets, and you are the first to get bumped.

Which jobs would I be qualified for with an Economics major and a minor in Statistics, besides an actuary?
I'm a nontraditional student with 10 years of full time work experience and 5 years of management experience--all in the restaurant industry.
Which jobs would I be qualified for with an Economics major and a minor in Statistics, besides an actuary?
It depends. Do you consider yourself a macro or micro guy? Anyway, you can work in the financial sector (not necessary in the insurance sector) as an analyst, you can work in some economic governmental agency as an economist, or you can teach. Those are some options, but from experience I would recommend working in the financial sector, getting some experience in finance beside economics and statistics, and then doing the CFA (Chartered Financial Analyst). For economist real money is actually in finance!

How are cancer statistics compiled? Who counts them?
I'm suspicious of cancer mortality statistics published by the government. What is a "survivor"? What is a "death?" Do people really die of one thing? What if they die from the treatment? Does early detection really alter the DATE of death or just the length of the period until death?
How are cancer statistics compiled? Who counts them?
As a cancer registrar it is my job to report all of this information to the government for the hospitals I work for. We stage the cancer, tell them what tests and treatment the patient had, if they were cancer free, alive or dead, etc. etc. We give them everything. It is required by law in every state of the United States. Each state gives the data to Washington DC and they give it to The World Health Organization as do all the countries that make up the United Nations. Researchers all over the world use this data and the government publishes the statistics.
The statistics are based on survival rates (how long the person lives) from the date of diagnosis and can be subcategorized by race, age, gender and stage at diagnosis.
No, people do not usually die of one thing. However, you can tell if early detection makes a difference if people with a stage 4 colon cancer live for a year after diagnosis and people with a stage 1 live for 10 years or more.
If someone dies and they were not cancer free at the time it is contributed to the cancer. If they were cancer free it is not.
Reply:Hi Neil. Your questions are valid and important, but not easy to answer.
First, for the latest cancer statistics use Pubmed to read this paper: CA Cancer J Clin. 2008 Mar-Apr;58(2):71-96. "Cancer statistics, 2008".
Cancer treatment is generally not very effective. The "war on cancer" has led to a dramatic increase in our understanding of the biochemical changes involved in carcinogenesis, but progress in treating most cancers has not been as rewarding.
Because of this poor treatment track record, cancer is the only disease that has a 'phony' definition of cure. A cancer is considered 'cured' if the patient survives 5 years after diagnosis. No other disease is considered cured if the patient survives 5 years after diagnosis!
I believe most cancer statistics (aside from the 5 year survival 'game') are legitimate (within the limitations of data collection). However, there are factors that are driven by scientific progress that can artificially 'change' cancer stats. A good example is the so-called "Will Roger's Phenomenon" (You can read many articles on this issue and cancer by going to Pubmed).
Will Rogers one said: "When the Oakies leave Oklahoma and move to California, they raise the average intelligence of both states!" So, how can this be true? It would be true if the intelligence of the Oakies is mid-way between those in California and the people they left behind in Oklahoma (Californians being dumber than Okies and remaing Oklahomans being smarter).
The Will Rogers Phenomena in Cancer has recently lead to 'improved' cancer survival statistics without any actual changes in cancer survival. Just 10-15 years ago, science could only seperate many cancers into 'early' or 'advanced' stages at the time of diagnosis. However, recent scientific advancements have enabled the identification of a third, intermediate, stage at diagnosis.
Generally, the new 'middle stage' of cancer severity was lumped into the 'early stage' groups. Now, it gets lumped into the 'advanced stage' groups. This results in better survival stats for both groups! - the Will Rogers Phenomenon!
Hope this wasn't too complex to be helpful.
Best wishes and good luck.
p.s. a few years ago my mother died from breast cancer. She survived more than 6 years after her initial diagnosis, so she went into the statistics as a 'cure'. Her funeral suggests otherwise.

As a cancer registrar it is my job to report all of this information to the government for the hospitals I work for. We stage the cancer, tell them what tests and treatment the patient had, if they were cancer free, alive or dead, etc. etc. We give them everything. It is required by law in every state of the United States. Each state gives the data to Washington DC and they give it to The World Health Organization as do all the countries that make up the United Nations. Researchers all over the world use this data and the government publishes the statistics.
The statistics are based on survival rates (how long the person lives) from the date of diagnosis and can be subcategorized by race, age, gender and stage at diagnosis.
No, people do not usually die of one thing. However, you can tell if early detection makes a difference if people with a stage 4 colon cancer live for a year after diagnosis and people with a stage 1 live for 10 years or more.
If someone dies and they were not cancer free at the time it is contributed to the cancer. If they were cancer free it is not.
Reply:Hi Neil. Your questions are valid and important, but not easy to answer.
First, for the latest cancer statistics use Pubmed to read this paper: CA Cancer J Clin. 2008 Mar-Apr;58(2):71-96. "Cancer statistics, 2008".
Cancer treatment is generally not very effective. The "war on cancer" has led to a dramatic increase in our understanding of the biochemical changes involved in carcinogenesis, but progress in treating most cancers has not been as rewarding.
Because of this poor treatment track record, cancer is the only disease that has a 'phony' definition of cure. A cancer is considered 'cured' if the patient survives 5 years after diagnosis. No other disease is considered cured if the patient survives 5 years after diagnosis!
I believe most cancer statistics (aside from the 5 year survival 'game') are legitimate (within the limitations of data collection). However, there are factors that are driven by scientific progress that can artificially 'change' cancer stats. A good example is the so-called "Will Roger's Phenomenon" (You can read many articles on this issue and cancer by going to Pubmed).
Will Rogers one said: "When the Oakies leave Oklahoma and move to California, they raise the average intelligence of both states!" So, how can this be true? It would be true if the intelligence of the Oakies is mid-way between those in California and the people they left behind in Oklahoma (Californians being dumber than Okies and remaing Oklahomans being smarter).
The Will Rogers Phenomena in Cancer has recently lead to 'improved' cancer survival statistics without any actual changes in cancer survival. Just 10-15 years ago, science could only seperate many cancers into 'early' or 'advanced' stages at the time of diagnosis. However, recent scientific advancements have enabled the identification of a third, intermediate, stage at diagnosis.
Generally, the new 'middle stage' of cancer severity was lumped into the 'early stage' groups. Now, it gets lumped into the 'advanced stage' groups. This results in better survival stats for both groups! - the Will Rogers Phenomenon!
Hope this wasn't too complex to be helpful.
Best wishes and good luck.

What kind of T-test to use for statistics class?
I am using a T-test to compare boys and girls on the number of total absences from school. I am able to assume equal variances according to the assignment. N=10 for girls and N=10 for boys. I believe this would be a two-tailed test. I have the calculation formulas, but I am not sure which one to use. Would I need to use an independent or dependent T-test equation formula? As usual, the book I have explains this in terms as if I was a professor of math. Thanks for your help!
What kind of T-test to use for statistics class?
small sample test for the difference in means
sample X and Y from normal data sets with the sample size of X being n and the sample size of Y is m
the test statistic is a student t
t = (xbar - ybar) / sqrt(var(X) / n + var(y) / m)
the degrees of freedom are:
((var(x) / n + var(y) / m)^2) / ((var(x) / n)^2 / (n - 1) + (var(y) / m)^2 / (m - 1))
this nasty looking equation is very simple if m = n. the degrees of freedom in that case are m + n - 2.
The p-value of the test is the area under the normal curve that is in agreement with the alternate hypothesis.
H1: d %26gt; 0; p-value is the area to the right of t
H1: d %26lt; 0; p-value is the area to the left of t
H1: d ≠ 0; p-value is the area in the tails greater than |t|
where d is the difference in the means, d = μx - μy.
Consider the hypothesis as a trial against the null hypothesis. the data is evidence against the mean. you assume the mean is true and try to prove that it is not true. After finding the test statistic and p-value, if the p-value is less than or equal to the significance level of the test we reject the null and conclude the alternate hypothesis is true. If the p-value is greater than the significance level then we fail to reject the null hypothesis and conclude it is plausible. Note that we cannot conclude the null hypothesis is true, just that it is plausible.
If the question statement asks you to determine if there is a difference between the statistic and a value, then you have a two tail test, the null hypothesis, for example, would be μ = d vs the alternate hypothesis μ ≠ d
if the question ask to test for an inequality you make sure that your results will be worth while. for example. say you have a steel bar that will be used in a construction project. if the bar can support a load of 100,000 psi then you'll use the bar, if it cannot then you will not use the bar.
if the null was μ ≥ 100,000 vs the alternate μ %26lt; 100,000 then will will have a meaningless test. in this case if you reject the null hypothesis you will conclude that the alternate hypothesis is true and the mean load the bar can support is less than 100,000 psi and you will not be able to use the bar. However, if you fail to reject the null then you will conclude it is plausible the mean is greater than or equal to 100,000. You cannot ever conclude that the null is true. as a result you should not use the bar because you do not have proof that the mean strength is high enough.
if the null was μ ≤ 100,000 vs. the alternate μ %26gt; 100,000 and you reject the null then you conclude the alternate is true and the bar is strong enough; if you fail to reject it is plausible the bar is not strong enough, so you don't use it. in this case you have a meaningful result.
Any time you are defining the hypothesis test you need to consider whether or not the results will be meaningful.
Reply:In order to use a t-test, you need to assume Gaussian distribution, i.e. a bell shaped curve if you plot each data point on a graph. If you don't have a Gaussian distribution you need to use a nonparametric test such as a Mann-Whitney. A two-tailed test is appropriate if you do not have a preconceived expectation about which way the data will go. An independent test would be used if the two variables (boys versus girls) are unrelated and one does not affect the other. If boys and girls were always skipping school together and one required the other, then a dependent test would be appropriate. Stats books suck and are virtually worthless for normal people.

How would I begin to find the answer using nature of estimation used in statistics?
Employees in a large accounting firm claim that the mean salary of the firm’s accountant’s is less than that of its competitor’s, which is $45,000. A random sample of 30 of the firm’s accountants has a mean salary of $43,500 with a standard deviation of $5200. At alpha = 0.05, test the employee’s claim.
How would I begin to find the answer using nature of estimation used in statistics?
This is a hypothesis test for the population mean.
H0: mu = 45,000
HA: mu %26lt; 45,000
Since n %26gt;= 30, then you can use a z test statistic.
z = (xbar-mu)/{sigma/sqrt(n)}
= (43500-45000)/{5200/sqrt(30)}
= -1.58
Keep in mind that I used s (the sample standard deviation) instead of sigma (the population standard deviation) in this expression. That is because the sample size is %26gt;= 30, so the sample sd is going to be close enough to the population sd, and we can substitute.
The one tailed p-value is 0.0571 from the standard normal table. Since this is greater than alpha, you would not reject the null hypothesis. The evidence does not suggest that the mean salary at this firm is less than $45,000.
Reply:Ho: μ=45000
Ha: μ%26lt;45000
x-bar=43500
n=30
σ=5200
Assuming all of the simple conditions are met, use the equation to find your z-score
z=(x-bar - μ)/(σ/√n)
z=(43500-45000)/(5200/√30)
z=-1.57997
Look up the p-value in a standard normal probabilities table
The p-value is 0.0571
You can conclude that the employee's claim is true is it is less that the α-level. Since the p-value is greater than the α-level, you cannot conclude that the employee's claim is true. (You fail to reject the null hypothesis.)

In statistics how do you know when to reject the null hypthesis or when to say fail to reject?
you reject your null when your P-value is less than a certain alpha level that you specify.
Hypothetically your P-value is .04923534635, you can reject your null at alpha = .05 but not at alpha = .01

How do we know that our sample is enough to represent the population in statistics?
I'm going to make a test about paired samples. They're non parametric samples. But i confused wether the samples is not enough to represent the population. So how do we know or what test should i do to make sure the sample is quite enough.
Thanks
How do we know that our sample is enough to represent the population in statistics?
If you are doing a paired-sample t-test, the rule of thumb would be a minimum of 30 participants, assuming the responses are normally distributed on both the pre- and post-tests.
My understanding is that in computer simulations drawing lots of different samples from a virtual population, n=30 is the smallest sample that has an acceptable probability of approximating a normal distribution.
If you want to do any regression or factor analyses, you should have a least n=100.

Whats the difference between inferential and descriptive statistics?
I mean, in English and not text book terminology, what is the difference?
Whats the difference between inferential and descriptive statistics?
Descriptive statistics are, as the name implies, used to describe the characteristics of the population from which your data are drawn. The mean, standard deviation, median, 25th percentile, 75th percentile, etc. are descriptive statistics.
Inferential statistics relates to hypothesis testing. Usually, you have a null hypothesis and you want to assess whether your data are inconsistent with your hypothesis. A t-test, for example, may be used for inferential statistics, as can confidence intervals.
As an example, I am a biostatistician and my work concerns clinical trials, in which we test drugs or other treatments on people. As a simple example, we might design a trial to test and active treatment (A) against a placebo (B). Subjects who qualify for the trial are randomized to receive either A or B, but the placebo is made to look like the active treatment, so usually neither the subject nor their physician know what they are getting.
The null hypothesis in such a clinical trial is that A and B are no different in their effect on a specific outcome. We then test whether our data are consistent with the null hypothesis of no difference. If we let Y(A) = the mean outcome for those randomized to A and define Y(B) similarly, then a test statistic is of the form T = (Y(A) - Y(B)) / SE where SE is the standard error (measure of precision) of the numerator. If T is large (usually larger than 1.96 or so, depending on sample size), then we reject the hypothesis of no treatment difference. We make the inference then that A is a better treatment than B for this particular outcome.
From the value of T, you can compute something called the p-value, which is the probability that you would have seen a value as large as your observed T just by chance if the null hypothesis is true. The smaller p is, the more evidence you have that the null hypothesis may be false. Usually, p %26lt; 0.05 is considered sufficient evidence to reject the null hypothesis.
Now, even if the true difference between A and B is small in clinical terms, you can make T large by designing a very large trial. So, there are two concepts to take into account: statistical significance and clinical significance. Many people make the mistake of relying only on statistical significance (p %26lt;= 0.05) to decide whether a new active treatment is worthwhile compared with placebo. They should also take account, however, of clinical significance, by which I mean asking whether the observed difference Y(A) - Y(B) is large enough that a doctor would want to adopt the new treatment for his/her patients. The statistical significance is purely inferential, but you can only assess clinical significance through descriptive statistics.
You really need to look at both, however, to assess the results of a trial. If you have statistical significance, then you can feel confident that there is a "real" difference between the active treatement and placebo. If you have clinical significance from assessing the magnitude of your observed treatment difference, then you would feel confident that the new drug has meaningful advantages over the placebo.
Sometimes, B is not placebo, but an active drug, but all of the above still is relevant.

What are some ways to track pool statistics?
My friends and I have wondered this last year about who is the best pool player among us. I said the only fair way is to take stats down over a period of time and compare. Is there a program, or what are some ways that I can track certain stats and share them online with others as it pertains to pool?
What are some ways to track pool statistics?
There are a lot of different pool stats you can try to keep track of, but they may not tell you a whole lot in the end. Most pool leagues track games won/lost and innings for each game. Obviously, the more games you win and fewer innings you take, the better you generally are. But you can get in to safety battles that will build up your innings or losing the game early, so it's not always an accurate reflection, although most formulas will try to account for it. I don't know the exact formulas any league uses, but Accu Stats lays out their Total Performance Average in the link below.
Otherwise, there are certain drills with scoring systems and you guys could each do them to track your progress. Granted, match play is different than practice drills, but it will give a general indication of your relative skill levels.
Reply:If you and your friends enjoy pool then form a team and join the American (or Canadian) Poolplayers Association. You play other teams weekly and can log into their website and get your weekly stats, plus you will have a lot of fun as well.
Reply:Just get a notebook and keep track of who wins the most

In statistics, what is the null hypothesis of no difference?
I need an easy to follow explanation please. I cant stand the jargons my txt book is using.
What is the opposite of this.
In statistics, what is the null hypothesis of no difference?
for a hypothesis test for no difference you have:
H₀: μ = 0 vs. H₁: μ ≠ 0
Consider the hypothesis as a trial against the null hypothesis. the data is evidence against the mean. you assume the mean is true and try to prove that it is not true. After finding the test statistic and p-value, if the p-value is less than or equal to the significance level of the test we reject the null and conclude the alternate hypothesis is true. If the p-value is greater than the significance level then we fail to reject the null hypothesis and conclude it is plausible. Note that we cannot conclude the null hypothesis is true, just that it is plausible.
If the question statement asks you to determine if there is a difference between the statistic and a value, then you have a two tail test, the null hypothesis, for example, would be μ = d vs the alternate hypothesis μ ≠ d
if the question ask to test for an inequality you make sure that your results will be worth while. for example. say you have a steel bar that will be used in a construction project. if the bar can support a load of 100,000 psi then you'll use the bar, if it cannot then you will not use the bar.
if the null was μ ≥ 100,000 vs the alternate μ %26lt; 100,000 then will will have a meaningless test. in this case if you reject the null hypothesis you will conclude that the alternate hypothesis is true and the mean load the bar can support is less than 100,000 psi and you will not be able to use the bar. However, if you fail to reject the null then you will conclude it is plausible the mean is greater than or equal to 100,000. You cannot ever conclude that the null is true. as a result you should not use the bar because you do not have proof that the mean strength is high enough.
if the null was μ ≤ 100,000 vs. the alternate μ %26gt; 100,000 and you reject the null then you conclude the alternate is true and the bar is strong enough; if you fail to reject it is plausible the bar is not strong enough, so you don't use it. in this case you have a meaningful result.
Any time you are defining the hypothesis test you need to consider whether or not the results will be meaningful.
Reply:I'm not really sure what the "null hypothesis of no difference" is but the "null hypothesis" is what you would expect if the results were totally random.
For example, say we are studying customers' color preferences, and they could purchase our product in 5 colors, equally priced, and essentially same, except for color. The "null hypothesis" is that each color would account for 20% of our sales because there are 5 colors and all else is equal. Now, if we find that say "brown" product accounts for 3% of sales and "green" accounts for 36% then we have found something that contradicts the null hypothesis and is therefore potentially interesting.
Don't know why people come up with flowery language to explain simple concepts.
Reply:By the expression "the null hypothesis of no difference," the textbook likely means the hypothesis that a population parameter (for example, the mean) is equal to some specific value. Such a hypothesis is used to test whether the population parameter is greater or less than that specific value (to some selected level of probability). So, the alternative hypothesis is that the population parameter is greater or less than that specific value. This alternative hypothesis is often called a two-sided hypothesis.
For contrast, often the test is whether a population parameter is less than some specific value. Then, the null hypothesis is that the parameter is greater than or equal to the specific value and the alternative hypothesis is that the parameter is less than the specific parameter. This alternative hypothesis is often called a one-sided hypothesis.

How do I do this standard deviation/statistics question?
The marks on an examination are normally distributed with a mean of 72% and a standard deviation of 8.1%. The top 20% of students are accepted into this college. To the nearest percent, what is the minimum mark the college will accept for entrance?
How do I do this standard deviation/statistics question?
You have to use z-scores. Using a z-score chart, find the z-score which will represent the lower 0.80 of the normal curve, leaving 0.2 (the top 20%).
z-score = (needed score - mean score)/standard deviation
Plug in and simplify.

What is different between Descriptive statistics and Inferential statistics?
Could someone help me with clear examples?
Thank you
What is different between Descriptive statistics and Inferential statistics?
Descriptive statistics just describe the data. So for example averages (means), highest, lowest, most common etc.
Inferential statistics are performed using statistical tests (T-Tests, ANOVAs, Regressions etc.). Instead of merely telling you what the data is, they tell you if the data is important.
So for example you may give two groups of people a test to perform. One of these groups gets given a particular drug, while the other group does not. Using differential statistics we can see what the average scores are for each group, but with inferential statistics we can see if they're significantly different.
Hope this helps.

Do Republicans make up their own statistics and polls, specifically for this election?
I have witnessed on many occasions, Republicans claiming that McCain will win the election by a landslide in Nov. I am just curious to know why are Republicans so confident that McCain will win the election?
Do Republicans make up their own statistics and polls, specifically for this election?
McCain will win because of the two pseudo-Marxist Democrats tearing each other apart, while he gets to run around and promote his American ideas.
Reply:Polls, for the most part, are flawed by design. Since the person doing the polling has free reign in choosing "who" they poll there is no way to ensure that they are unbiased.
For this reason I don't trust polls. For every poll you can find to support one opinion I can find one to refute it. Knowing all that, it's fair to say that anyone citing a poll is either:
1) full of it.
2) trying to sway opinion in their favor.
And for what it's worth, Republicans don't have the market cornered on quoting polls. One could ask:
"Do Democrats make up their own statistics and polls, specifically for this election? I have witnessed it on many occasions, Democrats claiming that Obama/Hillary will win the election by a landslide in Nov. I am just curious to know why are democrats so confident that Obama/Hillary will win the election?"
See what I did there? Doesn't make any less sense in the context of your question than the one you presented. Both sides do the exact same thing, it's the individuals bias to say one side is able to and the other isn't.
Reply:You don't really have to make 'em up - if you look hard enough, you can find a statistic that says - or can be twisted to say - what you want.
Take the instance you're talking about. Recent polls /do/ show McCain winning the general election. This is because the two democratic contenders are going negative on eachother. That's bringing them both down in the polls.
Meanwhile, there's very little negative campaigning being directed at McCain, at the moment, because there's no need to beat him, right now. He's effectively unopposed for the Rep nomination, so no one in his party is trying to beat him. And, both Dems are much more concerned with beating eachother.
Thus, he's doing well in the polls because people don't have a fresh negative image (or, possibly even no image at all) of him in thier minds when the pollster calls.
Once the Dem nominee is apointed by the DNC's superdelegates, that will change. Consider the kind of money Barrack and Hillary are raking in from those who want to own a piece of the next president. When tens of millions of dollars a month are being spent to go negative on McCain, his poll numbers will resemble Bush's.
Reply:I am an Independent but I would say it is due to the fact that there is serious division and hard feelings between the Democrats. Many of those Democrats claim that they will not vote for the other candidate if their choice does not win. It will not be a landslide, but if only a fraction of those who say this turn out to be true then the Republicans stand to win this election.
Nobody has a crystal ball to see the future and if the Democrats will be able to mend fences and join together against the Republicans but things don't look so good at the moment.
Reply:I'm not confident he will win, but Hillary and Obama have uncovered so much crap on each other that neither one has the huge following that they started with, I see this here on YA. While McCain isn't squeaky clean I think he will have fewer possible exploitable problems and he is liked by quite a few democrats that may be disappointed in their choices. As for polls, who knows?
Reply:no, I never seen that but I had seen Many Liberals done that.
Liberals love to use their IMAGINATION as FACTs.
Example:
"Kerry will win in a Landslide."
"War for Oil"
"Bush Lied, people Died."
Reply:because obama and hillary are doing a fantastic job of splitting their party. and for most thinking people ,the thought of obama or hillary is unconscionable.

Statistics? How to tell if it is a one tail or two tailed test?
If your hypothesis is that the two groups are not equal, then use a two-tailed test. If your hypothesis is that group A is larger (has a greater mean, for instance) than the control or group B, use a one-tailed (right) test. If your hypothesis is that group A is smaller, use a one-tailed (left) test.

What is the best online site(s) to view and/or buy vital statistics?
Looking for a good site to research online documents, especially death and birth certificates nationwide. Thank you.
What is the best online site(s) to view and/or buy vital statistics?
Are you asking this question from the USA, if you are there are a few sites that have these documents so I am told, but I am in the UK and I can say for certain there is nothing like that in the UK. I have a link to the one site I have used in the USA http://historyresearch.utah.gov/guides/d... it's brilliant.
Hope this helps.
Reply:There is a group for Kentucky vitals at www.rootsweb.com that will attempt to interpret Death Certificates of Kentuckians. The group is called Decipher.
Now, if you're talking about the united states as a whole, ancestry.com is probably your best bet to attempt to view bc/dc's. They also have a pretty good collection of WW1 and WW2 draft registrations.
For BC/DC's, you can also try individual state's vital records departments. I know if you have a relative who lived/died in TN, you can email vital records to have them do a search for a delayed birth certificate. If they find it, they will let you know what the charge is for getting a copy to you.
Other places, might be Yahoo and Google Images. I've found quite a few images through them of many vital records documents that were embedded in family websites.
www.findagrave.com might also have links to family vital records or the families might actually post a picture of a vital records at the grave of their loved one. Some even post the loved one's obituary.
Any of the photo housing sites such as flicker house a good many vital records that family members have posted. Try Flicker and Snapfish and any of the other photo sites by putting your surname in the search box.
Of course, there's nothing like family to give you copies of documents so try them also.
Good luck!
Reply:I have never heard of such and I have done plenty of genealogy research. I would be surprised if there is such a site, but If there is, the documents would have to be of people who are long, long dead. My vital stats is not public information, so you cannot go on-line to get it. Not every thing is open to the general public as free information that anyone is entitled to. Many such documents are protected by privacy laws, and are provided only in a need-to-know basis, like a legal investigation; or only to the immediate family, or direct descendants of individuals. And, even if the information was available to just anybody, who is going to do the work to put it all on the internet? It is not financially beneficial to the Dept. of Vital Statistics or Dept. of Health to spend countless man-hours, and dollars to put all that on the internet for free to everyone else.
If such a site does exist for such records of people who are long deceased, I would like to know too, so I can use it in my own genealogy research. It would make the research a lot easier!

The hospital you gave birth at should've sent the info to social security after she was born. You should've already rec'd a social security card. Contact your local social security office. You can go to the county she was born in %26amp; get a certified birth certificate for a nominal fee if you have proper ID %26amp; everything.

Statistics: To replicate a result I need 2 get the observations' deviation from the mean. How do I do it?
I am trying to replicate Robert Barro's results in his 1991 Economic Growth in a Cross Section of Countries paper. I have had problems with the deviation of PPP of investment. I don't know if I am just supposed to obtain the plain difference between the country's value and the sample mean or if this involves more extensive calculation.
Statistics: To replicate a result I need 2 get the observations' deviation from the mean. How do I do it?
The deviation of a value from the mean is the value minus the mean usually denoted as (x - xbar). However if you calculate all the deviations and add them together you will get zero, to avoid this, convention has it that we take the absolute value of each deviation, i.e. | x - xbar
Reply:|Its simple your over thinking it.
Deviation from mean = value - mean.
Its that simple.
Reply:the standard deviation has a formula sqrt n x p x q
the mean is n x p
n = no in sample that the mean measures
p = pr of the desired event happening
q = 1-p (ie event NOT happening)
Reply:we are talking statisics here, take the mean.
all stats are based on mean averages, do you know of any other?

Reply:It might mean "how many standard deviations is it from the mean" -- its z-score.
That means, you take the standard deviation, and you take the deviation of the observation. How many (or what percent) of the first is the second?
Say the standard deviation is .5, and the deviation of the observation is 1. It's 2 standard deviations. If the observation is .25, it's .5 standard deviations from the mean.
As I say, I can't be sure this is what you're looking for.

Statistics: To replicate a result I need 2 get the observations' deviation from the mean. How do I do it?
The deviation of a value from the mean is the value minus the mean usually denoted as (x - xbar). However if you calculate all the deviations and add them together you will get zero, to avoid this, convention has it that we take the absolute value of each deviation, i.e. | x - xbar
Reply:|Its simple your over thinking it.
Deviation from mean = value - mean.
Its that simple.
Reply:the standard deviation has a formula sqrt n x p x q
the mean is n x p
n = no in sample that the mean measures
p = pr of the desired event happening
q = 1-p (ie event NOT happening)
Reply:we are talking statisics here, take the mean.
all stats are based on mean averages, do you know of any other?

What is the difference between Page views and visitor numbers in the 360 statistics?
Just curious if page views includes yourself, and if visitor numbers are the number of unique people who have visited your 360 regardless of how many times.
What is the difference between Page views and visitor numbers in the 360 statistics?
Page views are (as implied) the number of times that page has been viewed (which could be by the same person or people).
Visitors is the number of individual viewers of that page.
So if I viewed a page 3 times, and you viewed it twice, it would have 5 page views, and 2 visitors.
Reply:You said so
Reply:Views are from the public and friends.
Reply:If one person looks at 10 pages or 10 people look at one page each you still have 10 page views.
Unique viewers will include yourself. If the same person comes back later, they could be counted as another unique viewer.

Is there anywhere I can find statistics for the number of US citizens that own homes in Mexico?
I have a ranch near Guadalajara. I am curious as to how many US citizens are buying up property down there.
Is there anywhere I can find statistics for the number of US citizens that own homes in Mexico?
I googled your question pretty much as you asked it and got about 500,000. I have friends near San Felipe in Baja Norte and I think that number is a little low. Some Americans prefer not to live in American colonies and I think the number does not reflect isolated Americans who prefer to live with the Mexican people, which is my preference Lots of Americans are buying property. In the San Felipe area, south of town, beachfront homes on the Sea of Cortez can be bought (99 year lease) for $60,000+. Contrary to popular belief, you can also own in fee simple. The major American realtors, like Coldwell Bankers, have offices throughout Mexico.
Reply:There are between 500,000 and 2 million Americans who have retired to Mexico. This is to take advantage of the lower cost of living

How accurate are the cancer-death statistics reported by the American Cancer Society?
I have checked with others and we are concerned that the fiqures are not accurate in regards to the number of deaths from cancer each year. Death certificates indicate death from respiratory or heart failure or some other condition. But these complications were the result of the cancer the person had. I don't believe the American people are being given a true picture about the number of deaths due to cancer each year. And what can be done to make the reports more accurate?
How accurate are the cancer-death statistics reported by the American Cancer Society?
The problems is that older ppl that have cancer have other diseases especially heart problems and they die from those other diseases before the cancer. It isn't the cancer that kills them.
Believe it or not there are many people that die of natural causes have cancer. It isn't misleading it is just the way it is.
You need to have a better understanding of cancer instead of your assuming false information of inaccurate reporting.

Statistics. Suppose you are the coach of a church basketball team and are asked how many ways?
you can assign positions to your players (that would be 5 different positions) with a roster of 11 players. Assume that any player can go into any position. How many possible ways can you position your players?
Statistics. Suppose you are the coach of a church basketball team and are asked how many ways?
If you have n objects there are n! permutations of these objects.
If you have n objects and select r of them you have n! / (n - r)! permutations of the r objects. This can be written as n P r.
here we have 11 P 5
= 11! / (11 - 5)! = 11 * 10 * 9 * 8 * 7
= 55440
Reply:Assuming the question is how many different 5-person lineups one can derive from an 11-player roster, then the answer depends on whether you want to differentiate lineups consisting of the same 5 players but arranged in a different order.
If so, then the answer can be found by calculating 11P5, which is 11!/(11-5)!, or 11*10*9*8*7 which is 55,440.
If arrangement is irrelevant, then you would calculate 11C5, which means you divide the above answer by 5! (5*4*3*2*1=120), which reduces your number of distinct lineups to 462.
Reply:P(11, 5) = 55,440
--------
Ideas: You have 5 different positions to fill players. So, you can have 11 choices to fill the first position, 10 the second position, and so on. 11*10*9*8*7 = 55,440

Is it possible to get crime statistics broken down by crime and by citizenzhip?
In my community, crime is up over the last year. Do you think it would be good to see the number of crimes committed by citizens and legal immigrants versus illegal?
Is it possible to get crime statistics broken down by crime and by citizenzhip?
It would be if a person was going to use that data to come to a logical conclusion, accept that conclusion and then takes steps to implement a fix if one is deemed nescessary.
However there is plenty of data to support the fact that illegal immigrants commit a very disproportionate amount of crime per capita.
But since people defending them just change the subject when you put the facts right in front of them it becomes sometimes an excercise in futility.
Reply:It would be interesting, but I would have to say the legal citizens commit alot more crime than illegals.In my small town where I live the crime rate has gone down 12% in the past 2 years and my twn has alot of illegals in it.

How can we use probability statistics to anticipate the future cost of health care premiums?
Wow that is a hard question to answer in this way.... While the TV show Numb3rs is fun and accurate like McGyver was years ago this is a very difficult problem. The thing is that each factor has to be given a number value. And the people whom do this for a profession are very good at handicapping those values. Once those values are assigned then the equations are out there and can be used.
Hope this helps.

How can I solve the Statistics problem below on power and ss?
the difference between means is .25. St. deviation is .67. What sample size is needed for a detectable difference with 90% power and alpha .05?
Also, if n = 30 per group, alpha is .05, power is 90%, what is the minimum detectable difference?
How can I solve the Statistics problem below on power and ss?
1)
First find the rejection region. for a 5% significance two tail test it is ±1.96 standard units about the hypothesized mean difference, 0, in this case.
The power of the test is the probability of being in the rejection region when the null hypothesis is false.
This is much easier to explain when I can draw the images. But oh well.
Now, although the test is two tailed and both tails should be accounted for, the lower tail's contribution to the power is so small i will omit it from the calculations.
the upper rejection region is 1.96 * 0.67 / sqrt(n)
the lower end point for the power is 0.25 - 1.28 * 0.67 / sqrt(n)
set these two equations equal to each other and solve for n.
1.96 * 0.67 / sqrt(n) = 0.25 - 1.28 * 0.67 / sqrt(n)
n = 75.39796
n must be integer valued, always take the ceiling to make sure you have the correct size
n = 76
== -- == -- == -- ==
find the rejection region
0 ± 1.96 * 0.67 / sqrt(30)
Dbar %26lt; -0.2397564 or Dbar %26gt; 0.2397564
the smallest detectable difference is ± 0.2397564

Can anyone help me with a business statistics question?
I can't understand my professor, and he's a bad teacher at that
question is
Does cocaine use by prgnant women cause their babies to have low birth weight? To study this question, birth weights of babies of women who tested positive for cocaine during a drug screening test were compared with the birth weights for women who either tested negative or were not tested, a group we cal 'other'. Here are the summary statistics. The birth weights are measured in grams
Positive test group, n=134, x bar = 2733, s=599
Other n=5974, x bar=3118, s =672
I doubt anyone will answer this, but if anyone does i appreciate it, i just don't get any of it.
Can anyone help me with a business statistics question?
i lost u at the question is...
plz rate as bestest ever cuz it issss!!!
Reply:OK. one step at a time
1) breathe
2) understand the question: does cocaine use cause low birth weight
3) what is normal birth weight? other's x bar (mean) is 3118
4) what to compare to? in the other group, going out 1 standard deviation in either direction (s) gives you a range of 68% of the population. which means that 68% of other birth rates are between 2446 and 3790 (x bar +/- s)
5) understand the results: the sample population mean (2733)is well within range of the population mean (3118)
6) translation to answer question: cocaine does NOT cause low birth weight
7) reasoning and explanation: at first glance, it seems like the answer should be less. however, the size of the sample compared to the population sample means that there will be a wider range of birth weights to make the shape of a bell curve. Where the sample means falls along the curve is just to the left of the middle making it reasonable to conclude that the weights are within the normal range.
8) breathe again, cuz now it's done.
I hope this helps!
Reply:Sorry cant answer that cause my mommy wint let me....
Reply:where x bar is the birth weight and s is the standard deviation? n is sample size?
Looks like you have a higher s in the other group and a lower birth weight. so I'd say the answer is yes
Reply:This is a large sample test for the difference in means.
the null hypothesis is H0: μ1 - μ2 ≥ 0
the alternate hypothesis is H1: μ1 - μ2 %26lt; 0
the test statistic is:
z = (xbar1 - xbar2) / (√( s1² / n1 + s2² / n2 ))
z = (2733 - 5974) / √( 599² / 134 + 672² / 5974 )
z = -3241 / 52.47105
z = -61.76739
the p-value for the test is:
p-value = P(Z %26lt; -61.76739) ≈ 0. in fact this probability is so low you could say it equals 0.
with such a small p-value we reject H0 and conclude H1 is true and that the positive test group has a smaller mean than the other test group.

3) what is normal birth weight? other's x bar (mean) is 3118
4) what to compare to? in the other group, going out 1 standard deviation in either direction (s) gives you a range of 68% of the population. which means that 68% of other birth rates are between 2446 and 3790 (x bar +/- s)
5) understand the results: the sample population mean (2733)is well within range of the population mean (3118)
6) translation to answer question: cocaine does NOT cause low birth weight
7) reasoning and explanation: at first glance, it seems like the answer should be less. however, the size of the sample compared to the population sample means that there will be a wider range of birth weights to make the shape of a bell curve. Where the sample means falls along the curve is just to the left of the middle making it reasonable to conclude that the weights are within the normal range.
8) breathe again, cuz now it's done.
I hope this helps!
Reply:Sorry cant answer that cause my mommy wint let me....
Reply:where x bar is the birth weight and s is the standard deviation? n is sample size?
Looks like you have a higher s in the other group and a lower birth weight. so I'd say the answer is yes
Reply:This is a large sample test for the difference in means.
the null hypothesis is H0: μ1 - μ2 ≥ 0
the alternate hypothesis is H1: μ1 - μ2 %26lt; 0
the test statistic is:
z = (xbar1 - xbar2) / (√( s1² / n1 + s2² / n2 ))
z = (2733 - 5974) / √( 599² / 134 + 672² / 5974 )
z = -3241 / 52.47105
z = -61.76739
the p-value for the test is:
p-value = P(Z %26lt; -61.76739) ≈ 0. in fact this probability is so low you could say it equals 0.
with such a small p-value we reject H0 and conclude H1 is true and that the positive test group has a smaller mean than the other test group.

Can anyone help with a statistics question?
It is claimed that a new drug for hypertension (high blood pressure) is effective in 70% of
treated patients. In a given experiment, seven patients were treated.
(a) What conditions must be satisfied for this to be considered a binomial experiment?
(b) Assuming that these conditions are met, find the expected number of successful treatments
and the standard deviation.
(c) Use R to find the probability that
(i) at least four patients will be successfully treated?
(ii) exactly four patients will be successfully treated.
(iii) no fewer than 3 and no more than 5 patients will be successfully treated.
Can anyone help with a statistics question?
a) the people are independent trials for the drug test with one of two possible outcomes, they are successfully treated or not.
b) expected number of successfully treated people is 7 * 0.7 = 4.9
in general for a binomial the expected number of successes is n * p where n is the number of observations and p is the success probability.
c) here is what to put into R. the %26gt; is the line to type and the number after [1] is the prob.
(i)
%26gt; sum(dbinom(4:7,7,0.7))

Did you know unemployment statistics are NOT based on those currently collecting unemployment?
A lot of times when liberals and Dems try and refute the good economic news, they say unemployment statistics are based on those who are currently collecting benefits, and ignore those who have already exhausted their benefits.
Nothing could be further from the truth. According to the Bureau of Labor Statistics, the unemployment data the government prepares every month, including the unemployment rate, is based on household surveys of 60,000 households.
Here's the link to the appropriate page http://www.bls.gov/cps/cps_htgm.htm Read it for yourself, it's only about 1 page long.
Did you know unemployment statistics are NOT based on those currently collecting unemployment?
Yep, I knew that.
Most people do not know, that only about 40% of the people who lose jobs, are eligible for unemployment benefits.
In some states like Florida, only 27% of the unemployed people are eligible for unemployment.
So it would be a completely unreliable means of determining the unemployment rate.
Most people do not understand, there is no government office that companies have to report too,when people are fired, laid off or quit.
There is no government office that companies report too, when they hire people either.
So the government has no direct way to accurately track unemployment or the new jobs created, or jobs lost.
Thats why the Department of Labor uses surveys to individuals for the unemployment calculations, and uses surveys to business's to determine how many jobs were lost or added each month.
Alot of myths like this, just keep going on and on, people never take the time to actually research it themselves and find out the truth.
Reply:No, I did not know that. I believed that it was based on those who are currently collecting benefits. Thanks for the info.
Reply:Yup, I did; now, if only we could get the press to report SIMPLE FACTS like this, perhaps the American public could begin to be informed as to how our society functions at a basic economic level. Anything above that will take an act of God.
Reply:I know that there are /two/ commonly-reported unemployment figures. One is gathered from unemployment rolls. The other is a household survey. The survey tends to be a bit higher, for the cited reason.
Reply:There is also a statistic called the "Natural Unemployment Rate". For people betewwn jobs, or who are otherwise out of the current workforce. The baseline number since 1975 has been 4-5%.
Reply:No I did not know that. Thank you for the info!

Why is energy not included in inflation statistics?
I have an undergraduate degree in business, and this one has long baffled me. Energy is unquestionably an indispensable part of people's daily lives - certainly just as, if not more, important than most of the items in the current CPI. So why has the global rollercoaster spike in energy prices had no apparent effect on inflation statistics? Tell an average American that "inflation for the last few years has been around 1 - 3%" and you'll rightfully be laughed at as on out-of-touch economist.
Why is energy not included in inflation statistics?
It's fine to provide a number without energy, or without any of a number of other things people buy that you want to account for separately for a variety of reasons. The problem is the use of the number in the way you described. If you tell an average american that core inflation, that is inflation less the following list of more volitile commodities, is [insert the number], they are going to look at you with glassy eyes and say huh?
So the press needs to do some work for once, and be more precise about what they are reporting, and add back in the information needed to make a useful number out of the core number.
I like the thing they do around thanksgiving every year, where they take the same items each year and talk about the overall difference in price, and also discuss which items went up and which went down, and why.
so for the typical american, in the context of daily life, we could have a typical consumption pattern and talk about how it changed in price from year to year.
but inflation measured with and without a variety of items are useful measures for various economic analyses. they just shouldn't be used as a one size fits all number.
Reply:Because our government does not want us to know the truth -- the true impact of deficit spending for subsidies, socialism and wars...
The politicians and the DemRep parties and the media are studiously avoiding discussion of the collapsing dollar and runaway national debt. The missing components for CPI calculations help that avoidance.
We've been brainwashed for so many years now that most voters believe there is an "acceptable rate of inflation" because it's "for the greater good".
Reply:Core inflation number is what you are referring to.
There are good reasons to exclude from these stats influences that are not coming from inside of the country. We want to measure the effect of activity inside the country.
Now there are also good reasons for having an inflation measure that does include imported inflation. This is particularly true when the country importing is such a big influence on total demand for imported goods.
So, there are good reasons to know both core inflation and total inflation. Knowing one does not mean we must ignore the other.
One effect of large scale imported inflation is that it takes money out of consumers' pockets so that they can not then stimulate excessive demand within the country. High prices for imports remove steam from the economy, even drag it down a bit, force people to cut prices to get a sale.
Reply:Food and Energy are axed because their prices are too volatile. They would skew any signs of true inflation. When I say true inflation, I mean things like the price you pay for a hair cut at the barber shop. If those prices are rising, the Fed needs to worry. But if the cost of fuel at the pump rises, its impact is ignored until it has an impact on the barber's business.
This is why Food and Energy is ignored when it comes to the CPI.
Reply:...and why isn't the cost of cars, college tuitions, food and housing?
Could it be that the inflationary index is bogus?

I want to know why statistics is important in psychology and education?
doing a paper and I have to state why ststistics is important in the field of psychology and education.
I want to know why statistics is important in psychology and education?
Most times statistics are used in psychology to measure whether the results of an experiment shows genuinely "significant" differences within the results, or whether all of the results fit within a single range.
For example, there have been studies which "appear" to show that boys' and girls' academic performance goes in non-synchronous waves.
If you measured the performance of all the pupils in a school in a certain year in a certain subject you could tell (using chi square, for example) whether the performance of the boys (as a group) was statistically different from the performance of the girls (as a group), or whether the performance of all the students in that year, in that subject, fell within the same "range".
If there is a significant difference you can use "standard deviations" as a measure of just how big the difference is.
(I don't have any URLs on hand, but you can look up "statistical significance" and "standard deviations" online.)

Reply:As my professors say... Numbers don't lie. People use numbers to lie.
Reply:who says you need stats in psych?
Reply:Because the capacity, knowledge, functions of the human mind in itself is impossible to measure. Statistics are necessary because people need measurements in numbers and mathematics to define things that they wil otherwise never have a way to understand.
Reply:to show a norm and how close or far from it ___ is. like a measuring stick.. its the only way to show that something is or isn't normal, since most people dont know what the norm is in those fields... since there is so much variety.
hope this helps
Reply:Just to add to what alot of people have already said, statisitics and statistical methods can also be used to test whether trends across large sets of data occur by chance. This can be used to test weaknesses across a educational systems (such as in the UK with educational League tables etc), or to test trends in the behaviour of large groups of people in psychological research.
Reply:in education and also psychology you need many times to judge the results of some accurance. you will guess it only using probality. you will have choices many times in these fields. when ask to choose one then you will only use statistics.. thats all
