Week 3:
This week we are comparing and contrasting epidemiological methods of research; case-control and cohort study methods. 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:
- What is the fundamental difference between the method you have chosen (either the case-control or cohort method) and the randomized controlled trial?
- What are the advantages and disadvantages of the study method you chose (case-control or cohort study)?
- What are the characteristics of a correlational study?
- 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?
Post your response to the DB. Your analysis should have in-text citations and utilize a scholarly voice with APA formatting.

According to Curly Cupp (2020), cohort method is an observational nonexperimental study that evaluates a population over time to seek a possible (at least statistical) association between exposure and outcome. Randomized controlled trials (RCTs) involve the researcher manipulating the interventions, which differs from cohort studies that observe naturally occurring phenomena. Cohort method is often used to evaluate the effects of changes in health or risk factors that possibly lead to the understanding of diseases causes or correlation in grouped populations. Cohorts can be prospective (gathering data going forward) or retrospective (looking at data already collected) (Curly Cupp, 2020). Often, in the presence of a statistical association between exposure and outcome, the Clinical Trial (experimental) is sought to confirm the hypothesis (Camargo et. al., 2019)….Kindly click the purchase icon to purchase the full solution at $5
