Peer reviewedKeselman, H. J.; Cribbie, Robert; Zumbo, Bruno D. – Journal of Experimental Education, 1997
Nonparametric and robust statistics (those using trimmed means and Winsorized variances) were compared for their ability to detect treatment effects in the two-sample case. The use of two specialized tests, designed to be sensitive to treatment effects when data distributions are skewed to the right, is not supported by the analyses. (SLD)
