Default RANK and CORRELATION

Thanks, but do I have to rank the students first. Also, the link you gave me
was not very helpful. Remember, I'm a new user. Therefore, could you
explain how this should and could be done? Thanks.

Hi Rebecca:

Excel has a built-in function to help you. See:

This article also outlines the mathe behind the function.

Greetings. I realize this is a simple statistical question, but I don't have
a statistics package (or any knowledge of statistics), but I am using EXCEL
2003. I would deeply appreciate your help because I can't figure out on my
own how to do this in EXCEL.

I have a column of numbers in random order (5, 33, 4, 76, 32, 46, etc.).
The lower numbers are "better" than the higher numbers (they are scores on a
test; higher numbers mean more mistakes). I have another column of numbers
also in random order (not ranked). The lower numbers are "better" than the
higher numbers (they are scores on another test; the higher the number, the
more the mistakes). I want to see if there is a correlation between the two
columns of test scores: that is, I want to find out if those who did well on
the first test (those with lower numbers) also did well on the second test
(those with lower numbers). Could you please tell me in simple English how
to do this?
