The researcher is analyzing the effects of two independent variables (year in college and type of college) on perceptions of academic cheating, which suggests the need for a two-way between-subjects ANOVA to understand the interaction and main effects. Upon finding significant results, a simple main effect test would be necessary to examine the effects of one independent variable at each level of the other variable. Finally, if significant interactions or main effects are found, post hoc tests would be required to determine which groups differ from each other. Thus, all these statistical tests would be needed to reach the conclusion described.
