The Effects of Violations of Data Set Assumptions When Using the Oneway, Fixed-Effects Analysis of Variance and the One Concomitant Analysis of Covariance.
Johnson, Colleen Cook; Rakow, Ernest A.
Research in the Schools, v1 n2 p61-75 Fall 1994
This research is an empirical study, through Monte Carlo simulation, of the effects of violations of the assumptions for the oneway fixed-effects analysis of variance (ANOVA) and analysis of covariance (ANCOVA). Research reaffirms findings of previous studies that suggest that ANOVA and ANCOVA be avoided when group sizes are not equal. (SLD)
