Cohen d statistics

WebThe odds ratio formula is as follows: Odds Ratio = (a*d)/ (b*c). Standardized Mean Difference: Cohen’s D is the most common method. It measures the standardized mean difference. It is computed as follows: Effect Size = (μ1-μ2)/σ. Correlation Coefficient: The correlation coefficient. WebThe function computes the value of Cohen's d statistics (Cohen 1988). If required ( hedges.correction==TRUE) the Hedges g statistics is computed instead (Hedges and Holkin, 1985). When paired is set, the effect size is computed using the approach suggested in (Gibbons et al. 1993). In particular a correction to take into consideration the ...
