question

For 7 nights, Pamela tracked the number of pages she read in her book before going to bed:

8 pages

7 pages

6 pages

9 pages

7 pages

6 pages

What was the mean number of pages that Pamela read?

pages

key idea

The mean is the average of the numbers. You find the mean by adding the numbers together and then dividing by the number of numbers in the group.

solution

First, count how many numbers are in the group.

There are 7 numbers.

Now add all the numbers together:

7 + 6 + 9 + 8 + 6 + 6 + 7 = 49

Now divide the sum by the number of numbers:

49 ÷ 7 = 7

The mean number of pages that Pamela read was 7.
