How do you find the mean of a stem and leaf plot?

Answer 1

Step 1: Determine the smallest and largest number in the data.

The game stats are as follows:

Blues Member Name Minutes Played

Gifford 22

Slavky 29

Harrison 22

Samon 31

Mantry 20

Lewing 12

Wilson 14

Larriby 24

Paston 13

Lebling 4

Waster 2

Canno 1

Looking at the stats, we see the number of minutes played ranges from a low of 1 minute to a high of 31 minutes.

Step 2: Identify the stems.

For any number, the digit to the left of the rightmost digit is the stem. For example, the number 31 has a stem of 3, while the number 29 has a stem of 2. A one-digit number like 4 has a stem of 0. Think ''04'' for 4.

Based on the range of 1 to 31, we need stems of 0, 1, 2 and 3.

Step 3: Draw a vertical line and list the stems to the left of the line.

Step 4: Fill in the leaves.

The first data value is for Gifford, who played 22 minutes. The stem is the digit on the left. The leaf is the digit on the right.

Let's enter Lebling's 4 minutes. The stem is 0 and the leaf is 4.

Entering the rest of the data:

Step 5: Sort the leaf data.

The stem-and-leaf plot is easier to interpret when each row's leaves are sorted from low to high.

And that's the stem-and-leaf plot for minutes played.
