Key measures include Cohen’s D and correlation coefficients, with suggested benchmarks for small, medium, and large effects. Effect Size in Psychology: Measuring Research Impact. In this context, while statistical significance tells us whether an effect is likely to be real or just a fluke of chance, effect size tells us whether that effect actually matters in the real world. Effect-size estimation.

An effect size is a value that reflects the magnitude of the relationship between two variables. This chapter introduces the idea of an effect size and shows why the effect size is generally a more appropriate index than the p value for summarizing the results of a study.
