A double stem and leaf plot is almost the same as a simple one, except you include each stem twice (the first being for leaf values from 0 to 4 and the second, 5 to 9). This is generally done to make long strings of data more manageable. Example:
2 | 0 1 1 2 3 3 4 5 5 6 7 8 9 (simple stem and leaf)
2 | 0 2 2 2 3 3 4 (double stem and leaf)
2 | 5 5 6 7 8 9

A double stem-and-leaf plot is also known as a back-to-back stem-and-leaf plot. Instead of there being a stem on the left side and its leaf on the right, the stem is in the middle, with a leaf on the right and a leaf on the left. It is used to compare sets of data. For example, the number of homeruns hit by National League teams vs. American League teams.
