Invalidation of Parametric and Nonparametric Statistical Tests by Concurrent Violation of Two Assumptions.
Zimmerman, Donald W.
Journal of Experimental Education, v67 n1 p55-68 Fall 1998
Uses computer simulation to study the effects on parametric and nonparametric statistical tests when assumptions of normality and homogeneity of variance are violated. Results reveal that nonparametric methods are not always acceptable substitutes for parametric methods in research studies when parametric assumptions are not satisfied. (SLD)
