Key: 15 | 4 mean 154

stem and leaf plots are used to easily see large amounts of data. usually, you take the first digits and place them on one side of the table- the stem side, and the rightmost digit on the left side- the leaf side.

for example, the number ten would be

1 | 0

or the number 135 would be

13 | 5

if you have more than one number, you separate them by a space. so 125 and 126 would be

12 | 5 6

For this list, the stem and leaf plot would look like this

15 | 4 5

16 | 2 3 4 8 9

17 | 1 8 8 9

18 | 1 3
