Step-by-step explanation:
the stem-and-leaf diagram only looks at the last digit (for the leaves) and all the digits before (for the stem). so, we have to put a "key" or "legend" on this diagram to show what we mean by the numbers in this plot. the ones digits will be the stem values, and the tenths will be the leaves.
the key would be :
key: "1 | 2" means "1.2"
we see that all numbers start with either 1, 2. 3, 4 or 5.
these are our rows. and each of these starting numbers is the stem of its row. the numbers are the decimal point are the leaves.
so, we get (ordered ascending)
1 | 2 2 6 7 8
2 | 2 2 6 9
3 | 2 3 3 4 7
4 | 2 3 4 4 4
5 | 0 2 3 5 6
