Second, we hypothesized that moral disengagement would vary as a function of classroom membership. This hypothesis was also confirmed. The Kruskal-Wallis Moral Disengagement from Bullying: The Effects of Gender and Classroom 287 test revealed that there was a significant effect of classroom on moral disengagement H(12) = 26.25, p < .01, η2 = .10. To sum up these findings together with the results of the preliminary analyses, significant effects of gender were found on both bullying and moral disengagement while classroom proved to have a significant effect on moral disengagement no significant effect on bullying.
