The document provides examples of stem and leaf plots used to organize and summarize different data sets. Stem and leaf plots break numbers down into "stems" which are placed left of the decimal and "leaves" which are right of the decimal. Three examples are given showing stem and leaf plots of temperatures, Babe Ruth's home runs by year, and ages of US presidents at inauguration.
