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 need to reduce skewness, which is what Fisher's z aims to do, and you can use Student's t approximation.

WebApplies the Fisher transformation to r to obtain z, where z = arctanh(r) z2r(z) Applies the inverse Fisher transformation to z in order to recover r, where r = tanh(z) zScore(r, r_0, n) Returns the Fisher z-score for Pearson correlation r under the null hypothesis that r = r_0. Approximately, the z-score follows a standard normal distribution.
