The power to detect main and interaction effects in a factorial design was determined when the Bonferroni method was used to control the overall rate of Type I error at a conventional five percent level. For sample sizes typical of educational research, the power of this procedure is shown to be considerably less than that of recommended standards. Alternative applications of the Bonfer-roni procedure are illustrated and discussed.
