Stem and Leaf Plots are used to display large amounts of data an a easy to digest format. In the above example the data consists of family members at a reunion identified by age. The plot is broken dow into its stem and leaf based on first and last digit of of the age. from this it becomes easier to identify where there are clusters in ages and what the ranges are within each cluster.
