Introduction

Used in a very general sense, effect size is the quantitative measure of strength in a statistical relation (e.g. correlations, differences of means, etc.) and it is defined as such in Wikipedia.

In the literature, the wording "effect size" is mostly used in meta studies, where it refers to various techniques that allow combining multiple effect-sizes. [1]
