"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 ...
