Fisher r to z
http://vassarstats.net/rdiff.html WebConvert a correlation to a z score or z to r using the Fisher transformation or find the confidence intervals for a specified correlation. r2d converts a correlation to an effect size (Cohen's d) and d2r converts a d into an r.

The Fisher Z transformation is a formula we can use to transform Pearson’s correlation coefficient (r) into a value (z r) that can be used to calculate a confidence interval for Pearson’s correlation coefficient.. The formula is as follows: z r = ln((1+r) / (1-r)) / 2. For example, if the Pearson correlation coefficient between two variables is found to be r = 0.55, then we would calculate ...
