Abstract

The main focus of this chapter is the process of formulating and testing hypotheses. Two basic ways in which hypotheses are tested is by either observations and/or experiments. In both cases the importance of uniformity of conditions and sample size is a central point. Two in-depth case studies, emphasizing the testing of hypotheses by observation, form the core of the chapter: physician John Snow’s mid-nineteenth century investigations into the cause of cholera and the search for the cause of the AIDS epidemic in the latter decades of the twentieth century.
