The research hypothesis for the interaction effect is that the effect of hours of the Syfy channel watched is dependent on gender. This means that there may be different effects of watching the Syfy channel on geekiness for men and women, and that the relationship between hours of Syfy channel watched and geekiness may differ for men and women. This is an example of an interaction effect, where the relationship between two variables (hours of Syfy channel watched and geekiness) depends on a third variable (gender).
