Complete the stem-and-leaf plot of the data. Ages of Park Volunteers 13 40 15 17 48 21 19 52 13 55 60 20 Ages of Park Volunteers Stem Leaf 1 1 3357 N 0 3 4 8 5 25 6 Key: 13 = years old

Answer 1

In order to make a stem and leaf plot, each observed value must first be separated into its two parts:

The stem is the first digit or digits;

The leaf is the final digit of a value;

so the graph will be

Steam Leaf

1 3,3,5,7,9

2 0,1

3

4 0,8

5 2,5

6 0

The key on this plot shows that the stem is the tens place and the leaf is the ones place.

the key is 1|3= 13 years old
