Learn statistical methods used in epidemiology and medical statistics with this free course. Explore cohort and case-control studies, estimate risks and odds ratios, calculate confidence intervals, and test for associations. Enhance your data analysis skills and interpret test results effectively.
This free course is concerned with some of the statistical methods used in epidemiology and more widely in medical statistics. Section 1 introduces cohort studies in which individuals are classified according to their exposure and followed forward in time to evaluate disease outcomes. Section 2 looks at models for cohort studies. Section 3 introduces case-control studies in which individuals are selected according to their disease status and past exposures are then ascertained. Section 4 covers testing for no association in cohort studies and case-control studies.
