I want you to consider how you might include an additional variable. This additional variable could be a numeric variable or a categorical variable. Here are some examples to help spur your creativity:

General Topic: Gender differences in rumination

Independent Variable: Gender Dependent Variable: Rumination

• if you're already studying the relationship between stress and sleep, you could add the variable work hours
• if you're already studying the relationship between social media usage and depression, you could add the categorical variable platform (e.g,. Facebook, TikTok, Twitter).

Once you've selected your new variable, answer the following in the discussion question:

1. What is your hypothesis about the main effect of the new variable
2. What is your hypothesis about the interaction effect of the new variable
3. (Bonus) Draw a figure and upload it to the discussion board that shows how you think the interaction might look
