When is Fisher's z-transform appropriate? - Cross Validated
https://stats.stackexchange.com/questions/62824/when-is-fishers-z...
I have understood that I can use Fisher's z-transform to calculate this by $z_{obs}= \displaystyle\frac{\sqrt{n-3}}{2}\ln\left(\displaystyle\frac{1+r}{1-r}\right)$ and finding the p-value by $p = 2P\left(Z>z_{obs}\right)$ using the standard normal distribution. My question is: how large $n$ should be for this to be an appropriate transformation?
Two Correlation Coefficients - VassarStats

Using the Fisher r-to-z transformation, this page will calculate a value of z that can be applied to assess the significance of the difference between two correlation coefficients, r a and r b, found in two independent samples. If r a is greater than r b, the resulting value of z will have a positive sign; if r a is smaller than r b, the sign of z ...

What is Fisher Z-Transformation? The normal distribution. The Fisher Z-Transformation is a way to transform the sampling distribution of Pearson’s r (i.e. the correlation coefficient) so that it becomes normally distributed. The “z” in Fisher Z stands for a z-score. The formula to transform r to a z-score is: z’ = .5 [ln (1+r) – ln (1-r)]

www.chegg.com › fisher-z-transformation-31
Fisher Z transformation is a method that transforms the Pearson’s correlation coefficient r to the normally distributed variable z. The Z in the Fisher Z transformation stands for the normal z -score. It is named after Fisher who developed this transformation. The uses of Fisher Z transformation are listed below:
Fisher transformation - Wikipedia

The Fisher transformation is an approximate variance-stabilizing transformation for r when X and Y follow a bivariate normal distribution. This means that the variance of z is approximately constant for all values of the population correlation coefficient ρ .
