Standard error calculation for more than one sample size


New Member
Hi all

I am conducting a meta analysis of pearsons r correlations. Whenever a study has presented more than one correlation I have averaged them into one correlation by converting them into fishers z scores. I now have the problem that I need to calculate a standard error and variance of the fishers z correlations , which requires one sample size. I am wondering if anyone knows how best to go about this please?
