    Definition

    A stem-and-leaf diagram, also called a stem-and-leaf plot, is a diagram that quickly summarizes data while maintaining the individual data points. In such a diagram, the "stem" is a column of the unique elements of data after removing the last digit. The final digits ("leaves") of each column are then placed in a row next to the appropriate column and sorted in numerical order. This diagram was invented by John Tukey.
