Say we were designing a social media research experiment using Instagram. Using social media (instagram) as an independent variable, how could I design a pretest experimental design about social media use?

1.) What could we manipulate as the independent variable? What are the various treatments or conditions?

2.) On what dependent variable could I expect the manipulation to have an effect? In other words, what is the dependent/outcome variable in your experiment?

3.) What could I choose as my research design (e.g., pretest/post-test; pretest only)? And why?

4.) What are some potential limitations of the designs?
