In this course we will explore Observational and Interventional study design types. Observational studies in epidemiology draw inferences from a sample where the researcher is not in control and are often retrospective and used to assess potential causation in an exposure-outcome relationship. Interventional studies are often prospective and are tailored to evaluate clinical outcomes. The commonly used designs to study health outcomes among humans, such as cohort, case-control, ecological and cross-sectional and case studies will be discussed. The strengths and limitations of each of the study designs will be explored while looking at the guiding principles for each design and interpretation of results using such designs
