This course prepares you at a foundational level to evaluate and critique conclusions drawn from epidemiological research. You will trace the historical development of epidemiology, learn to interpret key measures of disease and association, understand the logic of major study designs, and develop the critical thinking skills needed to identify bias and assess the strength of evidence. By the end of the course you will also appreciate the value and limitations of epidemiology as a tool for researching health and disease in populations.
