Web.25 = Medium effect size, .40 = Large effect size. When f = 0, that’s an indication that the population means are all equal. As the means get further and further apart, f will grow indefinitely larger. For f squared, the suggestions are: .2 = Small effect size, .15 = Medium effect size, .35 = Large effect size. Formulas for Cohen’s F Statistic WebAug 28, 2024 · Effect size is typically expressed as Cohen’s d. Cohen described a small effect = 0.2, medium effect size = 0.5 and large effect size = 0.8 Smaller p-values (0.05 and below) don’t suggest the evidence of large or important effects, nor do high p-values (0.05+) imply insignificant importance and/or small effects.
