Homework Answers
False
Because it is possible to have an interaction effect with no main effect it is the case when interaction are significant and the main effect is not.

1. True or False? T F For a two-factor experiment, the bigger the differences between the group means, the more likely it is that at least one of the F- ratios will be significant. TF If the interaction in a Two-way ANOVA is significant, then at least one of the two main effects also must be significant. TF If the F-ratio for factor A has df also must have df (2, 24) (2, 24) then the F-ratio for factor B...

A two-factor ANOVA investigated the effects of gender (males vs. females) and participation in a varsity sport: whether a student participates in a varsity sport or not (yes vs. no) on the numbers of hours spent studying per week. The following matrix represents the outcomes of this study. Participation in a varsity sport Yes No There is a main effect of gender and a main effect of "participation in a varsity sport", but no interaction There are main effects of...
