Stem and leaf plot

A stem-and-leaf plot is a type of graph that organizes data so that frequencies can be compared.

Example

The stem-and-leaf plot groups the football scores shown in the table. The first column represents tens, and the second column represents ones:

1 | 1 means 11.
2 | 5, 2, 7 means 25, 22, and 27.
3 | 1 means 31.

The plot shows that scores for most of the games were in the 20s.
