WebJun 1, 2006 · The definition of the correlation coefficient given by Fisher is as follows: r = S ( x y) S ( x 2) ⋅ S ( y 2) where x and y represent deviation from their respective means. … WebThe first step is to run the correlation analyses between the two independent groups and determine their correlation coefficients ( r); any negative signs can be ignored. The next step is to note, or write down, the sample sizes per each independent group. Then, using a statistical chart with z values and calculator, or an online calculator ...
