A stem & leaf plot is a device for presenting quantitative data in a graphical format. A basic stem plot contains two columns separated by a vertical line. The left column contains the stems and the right column contains the leaves. Stem and leaf plots show the frequency with which certain classes of values occur. These values in turn can be used to create a histogram.
The image above depicts a stem-and-leaf plot displaying that data on new housing starts in the USA.
