WebCohen (1988, S. 109) suggests an effect size measure with the denomination q that permits to interpret the difference between two correlations. The two correlations are transformed with Fisher's Z and subtracted afterwards. Webinterpret effect sizes in terms of the benchmarks identified by Cohen (1988): An effect size is small if it is near 0.2, medium if it is near 0.5, and large if it is near or larger than 0.8.
