A Review of the Panoply of Effect Size Choices.
Arnemann, Kelly
Some 23 journals in educational psychology and related fields, including two organizational "flagship" journals with circulations over 50,000, now "require" effect size reporting. This paper reviews some of the many effect size choices available to researchers. Effect size measures can be grouped into measures of association strength and measures of standardized mean difference. Another area of interest is that of effect sizes that address group overlap. Because there is no "one-size-fits-all," researchers must choose the best index for each study. The ability to perform meta-analysis and replication of research is determined by the inclusion of the effect size as a supplemental statistic. (Contains 1 table and 49 references.) (Author/SLD)
