Answer:
=========================
Given data
- 420, 369, 375, 382, 410, 376, 397, 411, 356, 387, 355, 373
We need to make a stem and leaf plot
Step 1
Rearrange the data in the ascending order:
- 355, 356, 369, 373, 375, 376, 382, 387, 397, 410, 411, 420
Step 2
Group the data as follows:
- 355, 356
- 369
- 373, 375, 376
- 382, 387
- 397
- 410, 411
- 420
Step 3
The first two digits form a stem and the last digits form a leaf.
Make a plot:
Stem | Leaf
- 35 | 5 6
- 36 | 9
- 37 | 3 5 6
- 38 | 2 7
- 39 | 7
- 41 | 0 1
- 42 | 0
