WebThe way to do this is by transforming the correlation coefficient values, or r values, into z scores. This transformation, also known as Fisher’s r to z transformation, is done so that the z scores can be compared and analyzed for statistical significance by determining the observed z test statistic. 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 …
