Once the data from an epidemiological study are collected and prepared in a suitable format, statistical analysis can begin. This chapter reviews basic statistical methods used for analysis of descriptive epidemiological studies, with numerous practical examples. While many statistical packages are available to aid statistical data analysis of epidemiological data, it is important that researchers understand these methods and appreciate the standards used in reporting study results. The additional purpose of this chapter is to outline the approaches used in reporting study results, and provide an introduction to the information required for measures of disease occurrence (or death) and their calculation.
