Stem-and-Leaf Plot
Example
For the given values below, make a stem-and-leaf plot.
Use the digits from 5 to 9 as the stem.
81, 56, 74, 52, 78, 81, 77, 91, 85, 60,
75, 69, 97, 84, 70, 67, 80, 74, 74, 88
Solution Use the digits from 5 to 9 as the stem.
81, 56, 74, 52, 78, 81, 77, 91, 85, 60,
75, 69, 97, 84, 70, 67, 80, 74, 74, 88
81, 56, 74, 52, 78, 81, 77, 91, 85, 60,

| 7 | 4 8 7 5 0 0 4 |
| 8 | 1 1 5 4 0 8 |
| 9 | 1 7 |
[1]
Write the tens in the Stem:
5, 6, 7, 8, 9.
Write the ones in the Leaf.
56
→ Stem: 5 | Leaf: 6
...
5, 6, 7, 8, 9.
Write the ones in the Leaf.
56
→ Stem: 5 | Leaf: 6

| 8 | 0 1 1 4 5 8 |
| 9 | 1 7 |
Key: 7|0 = 70 - [3]
[2]
Arrange the Leaf values in ascending order.
(0, 1, 2, ..., 8, 9)
(0, 1, 2, ..., 8, 9)
[3]
Pick one value and write the key.
The key shows the meaning of the Stem (tens) and the Leaf (ones).
The key shows the meaning of the Stem (tens) and the Leaf (ones).

Example
For the given stem-and-leaf plot,
find the number of values that are greater than 74.
Key: 7|0 = 70
Solution find the number of values that are greater than 74.
| Stem | Leaf |
|---|---|
| 5 | 2 6 |
| 6 | 0 7 9 |
| 7 | 0 0 4 4 5 7 8 |
| 8 | 0 1 1 4 5 8 |
| 9 | 1 7 |
Key: 7|0 = 70
| Stem | Leaf |
|---|---|
| 5 | 2 6 |
| 6 | 0 7 9 |
| 7 | 0 0 4 4 5 7 8 |
| 8 | 0 1 1 4 5 8 |
| 9 | 1 7 |
Key: 7|0 = 70
3 + 6 + 2 = 9 + 2
= 11

The values greater than 74 are colored:
75, 77, 78, ... .
75, 77, 78, ... .
