Show Summary Details


The exercises in this section deal with various kinds of rates, and other simple summary measures used in epidemiological studies. The main topics include how the measures are calculated, the questions to be asked about them, possible sources of bias, and the uses to which the information may be put, including the estimation of the individual's chances. Consideration is given to the definition of numerators and denominators and methods of collecting numerator and denominator information, and to survival studies. Confidence intervals, odds and odds ratios, validity of measures, and the internal and external validity of studies are explained. The section includes exercises on directly and indirectly standardized rates and their use. A self-test concludes the section.

Keywords: rates; risks; prevalence; incidence; bias; denominator information; survival studies; confidence intervals; validity; standardized rates
