Graphical Methods for Assessing Effect Size: Some Alternatives to Cohen's d
Wilcox, Rand R.
Journal of Experimental Education, v74 n4 p353-367 Sum 2006
Reporting effect size plays an integral role in educational and psychological research and is required by many journals. Certainly, the best-known measure of effect size is Cohen's d, which represents a substantial improvement over using p values. But Cohen's d is known to suffer from some fundamental concerns. The author's goal was to illustrate some graphical methods aimed at addressing those concerns. These methods can be applied in a wide range of situations, including situations in which the Wilcoxon-Mann-Whitney test is used.
