A stem and leaf plot is a way to organize numerical data. For instance, the above plot shows the number of students enrolled in a dance class for 12 years. The numbers 81, 84, 85, 86, 93, 94, 97, 100, 102, 103, 110, 111 are depicted. "The 'ones digit' and the 'tens digit and greater' of each data item is separated as leaves and stems respectively."
