Stem and Leaf Plot- An organized and systematic way of plotting large amounts of numerical data. Numbers are categorized based on leading numbers (stem), with remaining numbers placed horizontally next to these (leaf). The mean and median of the data set can usually be quickly identified in this way. This stem and leaf plot displays a data set of arm length in centimeters. The "stem" members represent the tens, and the "leaves" represent the ones' place. (http://myplace.frontier.com/~paulgriffith2/mathmodels/datacenters.html).
