Glass's δ
Glass's δ is an estimator of the population effect size that uses only the standard deviation of the second group. An effect size is a quantitative measure of the strength of a phenomenon. A population effect size based on means considers the standardized mean difference between two populations.
Glass's \[Delta] equals the differences between the first and second sample means divided by the second sample standard deviation.
