WebJan 24, 2013 · 1 when the null hypothesis states that ρ = 0; but when the null hypothesis states that ρ = some nonzero value, we must apply Fisher’s r-to-z transformation to both r and ρ and then use the z-test shown in Eq. 5. For regression coefficients, on the other hand, the t-test shown in Eq. 8 can be used regardless of the value of b*.
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 ...
