**Leah**, Thursday, March 6, 2008 at 5:39pmThank you, but I have another question. Would I have to square root r^2, because how else would I find the value or r?

**Count Iblis**, Thursday, March 6, 2008 at 5:45pmYes, but some scientists will refer to r^2 as the correlation coefficient while others will refer to r as the correlation coefficient. So, what you should do is take the square root and say something like

"the correlation coeffcient is given by r = 0.469".

And then it doesn't really matter if you had said:

"the correlation coeffcient is given by r^2 = 0.22".
