The above image, taken from http://math.albany.edu/~reinhold/m308/Assgnmt1_HowTo_files/lectu0textbox17.gif, shows a stem and leaf plot for adult height in inches and tenths of an inch. As would be predicted, one cans see a fairly normal bell curve developing in the data. While this type of plot gives the viewer both an idea of the distribution of data, it also provides access to the raw data. It should be noted, however, that if one leaf is heavily populated by high numbers and the neighboring leaf is populated by low numbers, it is possible to have gaps in data that are not represented in the overall outline of the plot.Wednesday, July 30, 2008
