Does anyone know of an online Fisher's r to z calculator that is reliable and accurate? Or, does anyone have a recommendation for how to set this up in EXCEL or another format? I need to take the average of several Pearson's correlations, and I was hoping to find a calculator that would expedite the process (versus using the r to z the table by hand).
Thanks in advance!
If you have cma (comprehensive meta anaysis) program, you will convert pearson correlation coefficient (r) into Fisher's z.
Hey,
Go through this link.

It will be helpful.
Hey there you probably already have the answer but just in case you or anyone else needs it for the future, try this excel sheet with the relevant formulas.

By the way,
just in case someone has the same problem:
The Excel Fisher function calculates the Fisher Transformation for a supplied value. The syntax of the function is: FISHER( x )
Much easier and allows to to transform as many values as you need with jus one click in your excel.
