Glass's delta
Alejandra Gonzalez-Beltran
Glass's delta is an estimator of effect size which is similar to Cohen's d but where the denominator corresponds only to the standard deviation of the control group (or second group). It is considered less biais than the Cohen's d for estimating effect sizes based on means and distances between means.
