Quizplus · Accepted Answer

A significant variation across levels of the second factor (type of employment) indicates an interaction effect between Factor A (gender) and Factor B (type of employment). Therefore, the correct answer is C, which represents an interaction effect. A main effect occurs when one factor has a significant effect on the dependent variable regardless of the level of the other factor. A post hoc test is used to compare specific pair-wise differences between groups after a significant interaction or main effect.
