Learning Goal: I'm working on a communications writing question and need a reference to help me learn. Keeping in mind the differences between randomized experimental studies and observational studies, please think of a hypothetical observational study of your interest and answer the following questions: 1) What is your research question? 2) Would this be a cohort study or a case-control study (and why have you chosen one over the other - think of whether you are dealing with a rare or common disease/outcome)? 3) What is your independent variable? 4) What is your dependent variable? 5) What data source(s) would you use? 6) How would you sample your cases or cohort and your control group (depending on the design you have chosen)? Please answer this question in 300 words or less in a word document and upload as your weekly response.
