Find the range of each set of numbers.

7, 7, 5, 4, 1, 9, 8, 8, 8, 5, 2

The range is the difference between the greater number and the lower number.

It would be 9 - 1 = 8

thank you Joy

To find the range of a set of numbers, you need to determine the difference between the highest and lowest values in the set.

First, let's arrange the numbers in ascending order: 1, 2, 4, 5, 5, 7, 7, 8, 8, 8, 9.

The highest value in this set is 9, and the lowest value is 1.

To find the range, subtract the lowest value from the highest value: 9 - 1 = 8.

Therefore, the range of the set of numbers is 8.
