From the research designs we’ve discussed, choose an initial strategy for causal inference. (You may revisit this choice as we go deeper into additional strategies throughout the term.) Describe your choice and explain why this is a good fit for your problem. Does your existing data set contain what you need for this strategy? If not, search for other data that will provide what you need.
Plot your two main variables together in a way that shows as much information about their relationship as possible. Describe what you can see and what that means for your thinking about your research question.
