Web28. apr 2016 · One way to do so is to use a t -test. (That's what R is doing.) In that context, you don't assess the fitted r value, you convert that r -score into a test statistic that is distributed as t. The equation is: t = r n − 2 1 − r 2. Although you are correlating two variables, this isn't a 2-group t -test. It is a one-sample t -test.
