title: [A simple method to determine and evaluate "effect size"].
abstract: Measurement of effect sizes is a practice that is increasingly encouraged, indeed required, by journals of psychological and social behaviour, in addition to the standard tests of statistical significance. This paper is a methodological note presenting the conceptual interest of the effect size, its main indicators and their interpretation.
