Step 2: Organize the Data into a Stem-and-Leaf Plot

Given grades:
89, 85, 75, 76, 63, 90, 88, 94, 71, 54, 95, 79, 83, 85

We'll sort the data first:

Sorted:
54, 63, 71, 75, 76, 79, 83, 85, 85, 88, 89, 90, 94, 95

Now create the stem-and-leaf plot.

| Stem | Leaf |
|------|------|
| 5 | 4 |
| 6 | 3 |
| 7 | 1, 5, 6, 9 |
| 8 | 3, 5, 5, 8, 9 |
| 9 | 0, 4, 5 |
