WebMar 30, 2024 · 0.2 = Small effect size; 0.5 = Medium effect size; 0.8 = Large effect size; In our example, an effect size of 0.29851 would likely be considered a small effect size. This means that even if the difference between the two group means is statistically significantly different, the actual difference between the group means is trivial.
