This tool allows you to see the effect size (d) and percent overlap for any comparison between males and females. Enter the mean and standard deviation below for each group. If you have the standard error instead of the standard deviation, check the box to enter it and the sample size (n).
This tool assumes both distributions are normal. Effect size is based on Cohen’s d. Overlap is based on Weitzman’s ∆.
