WebMy understanding is that the Fisher's transform is used because the r's are not normally distributed. Therefore, it seems that the transform makes sense if one is just comparing a single r-value to 0 (i.e. in lieu of testing against a t-distribution with the test statistic t = r ∗ n − 2 1 − r 2 ). However, in my t-test, I am comparing the ...
