In statistics, an effect size is a quantitative measure of the magnitude of a phenomenon .
An effect size is exactly equivalent to a ‘Z-score’ of a standard Normal distribution. For example, an effect size of 0.7 means that the score of the average person in the experimental group is 0.7 standard deviations above the average person in the control group.
