A researcher is interested in examining how different social media platforms influence self-esteem. She randomly assigns a group of users to use only Tik Tok, only Instagram, or only Facebook for one month and compares their self esteem.

1. What is the independent variable in this scenario?

2. How many levels are there for the independent variable?

3. What is the dependent variable?

4. What is the confound for (you may list more than one, but you must give at least one!).

5. How could the confound be fixed in Scenario C? Be sure to tell mewhat technique you are using (constancy, repeated measures, randomization, elimination, or balancing), as well ashow you would apply that technique to this specific scenario, andhow that would fix this confound.
