1904,

Good catch.  Two typos - that everybody else figured out.  If you do the math and follow the logic, then you'll see those should be 500 - not 50, but my point is the same.

The idea that statistics branched off from mathematics is a widely held misconception. Some place an undue emphasis on the relationship, but the two disciplines are very different.

The purpose of descriptive statistics is to communicate information, while inferential statistics is used to reach conclusions and deductions that possibly explain the data. Both of these together make up applied statistics. There is also a discipline called mathematical statistics, which is concerned with the theoretical basis of the subject.


More plagiarism.  Have you any ability to think on your own?

Good Boy Noddy. You fetched the bone. Good Boy Noddy.

Here's some more - you're on the clock..... go  for it:

Refer: www.mentalfloss.com
"A stupid or silly person named NoodleNush a dolt. A person named CarryB whose mental acumen is well below par. A person of moderate to severe mental retardation having a mental age of from three to seven years and generally being capable of some degree of communication and performance of simple tasks under supervision. Namely CarryB. The term belongs to a classification system no longer in use and is now considered offensive, except if used correctly."

Go Boy.

9x6 = 54.
Oops. That's plagiarism. My teacher said it first.

I have many original thoughts. Sadly all of which would pass over your head like Swissair - you're too shallow and undeveloped. 

When the polyshop biz grinds to a halt you can always write out parking tickets and tell the public about all the research behind parking meters.

There are thousands of polygraph tests done each year, and yes there are and will be errors (as it the case with any test), so a few anecdotal stories do not support anything. 


Quote:
When we run tests in the field, we do confirm some of them independently.

  For example, I ran tests in one case that we .....

That is why there is a desire for polygraph and truthfulness testing of all sorts.


Quote:
Any test that discriminates truth from lies at better than chance rates, no matter how poor


Quote:
If, however, we introduce polygraph,(test) what will happen?  Assume a polygraph (test) is 80% accurate.


RE: POLYGRAPH TESTS
Refer Letter elsewhere on this site by:

John Furedy, Emeritus Professor of Psychology
University of Toronto
Sydney, Australia 

"The Polygraph “Test” Is Not A Test"

"What one would think if one heard that IQ tests “varied among agencies”. Wouldn’t one conclude that these so-called tests were not tests at all, but rather unstandardized interviews where IQ “testers” arrived at their scores by having a conversation with the examinee to determine the examinee’s IQ?  Why is it that even North American scientists commonly accept the polygraph as a “test”, and then go on to argue about validity, whereas the argument about validity cannot even begin if one is not dealing with a test.
It would be bad enough if faith in these polygraph “tests” were confined to talk show hosts like Dr. Phil, who deal with personal problems.  What is worse is that national security depends on this peculiarly North American superstitious flight of technological fancy."
