The Importance and Effect of Sample Size
About 50 to 100 different measures of effect size are known. Many effect sizes of different types can be converted to other types, as many estimate the separation of two distributions, so are mathematically related. For example, a correlation coefficient can be converted to a Cohen's d and vice versa. These effect sizes estimate the amount of the variance within an experiment t… WebMar 10, 2016 · If you look at a study that meets BEE standards and students were matched before being (non-randomly) assigned to treatment and control groups, then the average effect size is +0.32.
