WebFisher's r-to-z transformation happens to be a rather effective normalizing transformation (even though this is not the primary purpose of the transformation -- see below). Many meta-analytic methods assume that the sampling variances of the observed outcomes are (at least approximately) known. For example, for the raw correlation coefficient ...

WebThis 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 on the z scale, and then back-transform using its inverse transform, the hyperbolic tangent, or tanh.

Fisher z
Weba statistical procedure that converts a Pearson product-moment correlation coefficient to a standardized z score in order to assess whether the correlation is statistically different from zero. The test is useful in providing a normally distributed statistic (called the Fisher transformed value or Fisher’s z) that can be used in hypothesis ...
