Section 11-5
Stem & Leaf Plots
A stem & leaf plot organizes data points by the place value of the leading digits. For example, in a data set {23, 24, 27, 31, 33, 34, 35, 35, 37, 41, 49}, the tens digits would be the "stems", and the ones digits would be the "leaves".
Example:
Make a stem-and-leaf plot for the data set:
{0.1325, 0.1329, 0.1331, 0.1332, 0.1332, 0.1333, 0.1337, 0.1344, 0.1348, 0.1351}.
The digits 0.13 are common to all data points. So arrange 0.132, 0.133, 0.134, and 0.135 in the left column.
Be sure to include a "key" to show the place value that is meant. In this case:
