Namely, h = 0.2 is a "small" difference, h = 0.5 is a "medium" difference, and h = 0.8 is a "large" difference. Only discuss differences that have h greater than some threshold value, such as 0.2.; When the … WebHere are his guidelines for an unpaired t test: •A "small" difference between means is equal to one fifth the standard deviation. •A "medium" effect size is equal to one half the standard deviation. •A "large" effect is equal to 0.8 times the standard deviation.

WebCohen [1] suggested the following interpretation for f when used in ANOVA / ANCOVA: .10 = Small effect size, .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:
