Reading stem and leaf plots
A stem and leaf plot displays data by breaking each data point into two parts: the "stem" and the "leaf." Each stem represents a range of values (e.g. if the stem is 2, the corresponding leaves might be data points in the 20s). Each leaf typically represents the last digit of a data point (e.g. if the leaf is 6 next to a stem of 2, it could represent a data point whose value is 26). Created by Sal Khan.
