formulate a research question that lends itself to an observational study design (including an intervention component). After formulating your question, identify and describe how you would use a particular observational design to answer your question. Discuss the data collection methods you would employ (e.g., different survey types, etc.). Provide a rationale for why you chose the particular methods to answer the question, as well as the strengths and weaknesses of your study design.
