A stem and leaf plot is used to display quantitative rather than qualitative data. The data is further divided by using a stem and leaf system. The stem is the first part of the number while the leaf provides the rest of the data. For example, the a stem in the photo above for GNP per capita in Western Africa is 1-8, representing the hundreds place. The numbers on the right hand side would be considered the leaf, containing the tens place. So if the stem is 3 and the leaf is 70, the GNP would be $370.
