title: Redefining the confidence interval.
abstract: The confidence interval, its close cousin the p-value, and other statistical summaries of data are widely used in science, including the occupational and environmental health sciences, but they are almost as widely misused. My purpose here is to review some basic matters that should be covered in every introductory statistics course, but are generally omitted. More specifically, some of the many assumptions that are needed in the usual forms of analysis are reviewed.
