An Evaluation of Alternative Methods for Computing Standardized Mean Difference Effect Size.

Taylor, Matthew J.; White, Karl R.

Journal of Experimental Education, v61 n1 p63-72 Fall 1992

Results obtained in a metanalysis using indirect alternative methods of computing standardized mean difference effect sizes (SMDESs) were compared with results obtained from direct calculations of SMDESs. In most cases, alternative methods yield very comparable results and are beneficial to use, especially when sample sizes are large. (SLD)
