Stem-and-leaf Display:
A statistical technique for displaying a set of data. Each numerical value is divided into two parts:the leading digits become the stem and the trailing digits the leaf
note: the advantage of the stem and leaf display over a frequency distribution is we do not lose the identity of each observation.
Colin achieved the following scores on his twelve accounting quizzes this semester: 86, 79, 92, 84, 69, 88, 91, 83, 96, 78, 82, 85. Construct a stem-and-leaf chart for the data.
| Stem | Leaf |
| 6 | 9 |
| 7 | 8 9 |
| 8 | 2 3 4 5 6 8 |
| 9 | 1 2 6 |
