Hi!
Say I have a least squares regression line/ line of best fit like this:
Hand span = 2.3 + 0.53 X Age
and I'm wanting to find "r", "pearsons correlation coefficient"
How do I do it? I can use a calculator
Thanks so much guys!!!

You need to share your data before you can you find r; r is the correlation between your Age data and Hand Span data.
From the line you've given, r can be 1 or .01 for all we know; the line is simply a best fit.

There is a good explanation at http://www.answers.com/topic/coefficient-of-determination
There are many programs that will do the calculation. Excel has one, or you can find one on line.
