| Effect size | is a way of quantifying the difference between two groups. For example, in this study, one group of classes has had an 'experimental' treatment and the other has not (the 'control'). The effect size is a measure of the effectiveness of the treatment. An effect size of 0.4 for example means that the average person in the experimental group is higher than 66% of the control group. |
