G Power Effect Size D. Out of three smallmedium or large options for effect size in g power how to justify the selection if we have to directly place the value rather than calculating it separately while performing. GPower display of a post-hoc power.
Enter partial eta squared n2 which is the effect size measure indicating the total variance in testing explained by the within subjects variable eg time of testing. GPower supports both a distribution-based and a design-based input mode. Approximate eta squared size conventions are small 002 medium 006 large 014.
