Abstract
A percentile is a point below which a given percentage of the cases occur. For instance, 67 percent of the cases are below the sixty-seventh percentile, which is written as P 67. The middle of a distribution, or the point below which 50 percent of the cases lie, is, of course, the fiftieth percentile. In Chapter 2 we learned another name for this value—the median. The median is probably computed, used, and discussed more than any other percentile.
