WebUsing 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 …

WebFisher (1890–1962): even though r usually has an awkward skewed distribution, the inverse hyperbolic tangent, or atanh, of r is much better behaved. This transform, within statistics often labeled Fisher’s z, is said to be normally distributed to a good approximation. The basic tactic is now evident: apply standard normal-based technique
