WebMay 12, 2024 · This effect size is \(r^2\), and it is exactly what it looks like – it is the squared value of our correlation coefficient. Just like \(η^2\) in ANOVA, \(r^2\) is interpreted as the amount of variance explained in the outcome variance, and the cut scores are the same as well: 0.01, 0.09, and 0.25 for small, medium, and large, respectively. WebThe Cohen's d statistic is calculated by determining the difference between two mean values and dividing it by the population standard deviation, thus: Effect Size = (M 1 – M 2 ) / SD. SD equals standard deviation. In situations in which there are similar variances, either group's standard deviation may be employed to calculate Cohen's d.
