WebTwo, the provided formula for calculating r uses simple averaging [.5(r 1 +r 2)]. To yield a more accurate indicator of r, I have used Fisher's r-to-Z tranformation, averaged, and reversed back from Z-to-r. Nonetheless, the computation of s in the Z 1 * formula is relatively robust against minor deviations. In using this calculator, you are ... WebThe correlation, r, observed within a sample of XY values can be taken as an estimate of rho, the correlation that exists within the general population of bivariate values from which the sample is randomly drawn.
