Select either the case-control or cohort study method and compare its features, the methodology, to a randomized controlled trial using the following questions. Please format, organize, your responses using each question below: 1. What is the fundamental difference between the method you have chosen (either the case-control or cohort method) and the randomized controlled trial? 2. What are the advantages and disadvantages of the study method you chose (case-control or cohort study)? 3. What are the characteristics of a correlational study? 4. Where does the method you chose (case-control or cohort study) fall on the research pyramid? What does where it is on the research pyramid mean?
