- What is the confound for Scenario D (you may list more than one, but you must give at least one!).
- How could the confound be fixed in Scenario D? Be sure to tell me what technique you are using (constancy, repeated measures, randomization, elimination, or balancing), as well as how you would apply that technique to this specific scenario, and how that would fix this confound.
