WebCalculate the value of Cohen's d and the effect-size correlation, r Y l, using the means and standard deviations of two groups (treatment and control). Cohen's d = M 1 - M 2 / s pooled where s pooled =√[(s 1 2 + s 2 2) / 2] r Y l = d / √ (d 2 + 4) Note: d and r Y l are positive if the mean difference is in the predicted direction. WebPlot pooled effect - random effect model: option to include the pooled effect under the random effects model in the forest plot. Diamonds for pooled effects: option to represent the pooled effects using a diamond (the location of the diamond represents the estimated effect size and the width of the diamond reflects the precision of the estimate).
