How to calculate and interpret effect sizes Effect sizes either measure the sizes of associations between variables or the sizes of differences between group means. Cohen's d Cohen's d is an appropriate effect size for the comparison between two means. It can be used, for example, to accompan...
Hedges' g, which provides a measure of effect size weighted according to the relative size of each sample, is an alternative where there are different sample sizes. (This is important! If you've got different sample sizes then you should use Hedges' g.) ...
I realize how silly this is, especially for a game whose pinnacle of weaponry is a Super Monkey Storm, but it's fundamental to my motivation for game playing - if the reward for succeeding has lost it's meaning, then I don't get a positive pavlovian response to it, and I lose my ...

Effect sizes such as Cohens d , however, arestatistics and not relevant to decision-making. This article introduced an alternative formulation of Cohens d based on a "minimal important percent difference" (MIPD) between groups that has an intuitive, practical meaning. Cohens d was calculated ...
I contend, however, that the standardizer chosen for delta*, meaning the units in which it is expressed, is appropriate for inference but causes delta* to be inconsistent with conventional Cohen's d. In addition, delta* depends on the relative sample sizes in the particular experiment and, ...
