How to find Cohen’s D to determine the Effect Size Using Pooled Standard Deviation

This statistics video tutorial explains how to calculate Cohen’s d to determine if the size of the effect is small, medium, or large based on the differences between two sample means. This video also provides two ways to calculate the pooled standard deviation.
