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, ra
, found in two independent samples. If ra
is greater than rb
, the resulting value of z will have a positive sign; if ra
is smaller than rb
, the sign of z will be negative.
To perform the calculation, enter the respective values of r and n for the two samples into the designated cells, then click the «Calculate» button.
