Stem-and-Leaf Plots
A stem & leaf plot organizes data points by the place value of the leading digits. When making a stem & leaf plot, each item of data is separated into two parts. The “stems” usually consist of the digits in the greatest common place value of each item of data. The “leaves” contain the other digits of each item of data. 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:
