This document contains 3 stem-and-leaf plots showing the ages of US presidents and vice presidents from 1800 to 2008, as well as a frequency table showing the number of Republican and Democratic presidents during that time period. The author chose stem-and-leaf plots to organize the age data because they are good for large data sets and easy to read, and used a frequency table for the party data because there were fewer entries and it is simple. They include an example bar graph that could be used to visualize the party frequency data.
