This assignment describes the two types of analytic study types in health research. Observational study which includes cross sectional, case-control and cohort are discussed. Randomized controlled trials are briefly discussed as an example of experimental study design. The three major research designs are describes, contrasted and discussed as well as the strengths and limitations.

Zusammenfassung der Kapitel (Chapter Summaries)
The paper first introduces the concept of research design in health research, emphasizing the importance of selecting an appropriate design for the study. It then delves into the two major categories of analytical studies: experimental and observational. Experimental design is primarily associated with randomized controlled trials (RCTs), which are recognized as powerful tools for investigating the effectiveness of interventions. The paper highlights the role of random allocation in ensuring that all other potential causes are equal between treatment groups, making RCTs ideal for establishing cause-and-effect relationships.
The paper then shifts its focus to observational studies, which do not involve interventions. It examines the three main types of observational studies: cohort studies, cross-sectional studies, and case-control studies. Cohort studies are particularly useful for investigating the incidence and natural history of conditions. They can be either prospective or retrospective, with prospective studies following a group of people over time to observe the development of a specific outcome. Retrospective cohort studies utilize data collected for other purposes, offering a cost-effective approach but potentially lacking complete information on relevant variables.
