Download Lecture Overview
00:00 So what have you learned? You're now familiar with the main observational study designs, the cohort, the case-control, the cross-sectional and you know the difference between prospective, which moves forward in time and the retrospective, backwards in time. You know why matching is done, to control for certain confounding influences, and you know when some designs are more appropriate than others, using those characteristics like, which is rarer, the exposure status or the outcome status. Thank you.

Very through and the fact that most lectures had summaries of the previous video made it very easy to understand.
