User Review the different types of observational study designs presented in the Learning Resources: ecologic, cross-sectional, case-control, and cohort. Carefully examine the characteristics, strengths, and limitations of each design. Consider when it is appropriate to use each of the observational study designs. Consider how using observational study designs can lead to improvements in population health. Review the two articles assigned, with a critical eye toward the researchers’ use of study design and their selected methods. Whittle, R. S., Diaz-Artiles, A. (2020).
