Question

Find the range of the following set of data.
13. 11, 4,5,6, 9, 10, 12, 15, 16​

Answer 1

12

Explanation:

The greatest value in the data is 16.

The lowest value in the data is 4.

The range is the difference between the highest and the lowest values.

range = 16 - 4 = 12

Answer 2

12

Explanation:

First put the set in order from least to greatest:

4, 5, 6, 9, 10, 11, 12, 15, 16

To find the range you subtract the largest number by the smallest number.

4, 5, 6, 9, 10, 11, 12, 15, 16

So 16 - 4 = 12

So the range is 12.
