WebbCohen's d measures the DIFFERENCE between two variables' means divided by the Standard Deviation. If two groups have similar standard deviations and have the same group size, use Cohen's d. Note: It can only be used with normal data distributions. Cohen's d Effect Size categorization: d = 0.2 SMALL (0.2 means the difference between the two ... WebbThe minus results you have obtained is a result of subtracting the larger mean from the smaller mean in calculating d. If you reverse the order, subtracting the smaller from the larger, you will ...

Webb30 jan. 2024 · Meta-analyses of a treatment's effect compared with a control frequently calculate the meta-effect from standardized mean differences (SMDs). SMDs are usually estimated by Cohen's d or Hedges' g.
