Not sure whether a Fisher's z transform is appropriate here. For H 0: ρ = 0 (NB: null hypothesis is for population ρ, not sample r ), the sampling distribution of the correlation coefficient is already symmetric, so no … In statistics, the Fisher transformation (or Fisher z-transformation) of a Pearson correlation coefficient is its inverse hyperbolic tangent (artanh). When the sample correlation coefficient r is near 1 or -1, its distribution is highly skewed, which makes it difficult to estimate confidence intervals and apply tests of significance for the population correlation coefficient ρ. fmcsa tpr check
