The following are true of a stem-and-leaf plot:

• Data is displayed using two parts. The separated left column is called the "stem," and the row to the right of the separated column contains the "leaf" or "leaves."


• Every data point is listed, including those that are repeated.


• The length of the line containing the leaves next to a single stem corresponds to the height of the vertical bars on a histogram while allowing individual data points to be known.
