What is the range?

-9-9-6-5-9-6-7

The range of the given data set is 4.

Step-by-step explanation:

Given data set is 9, 9, 6, 5, 9, 6, 7 Here the least value is 5 and the maximum value is 9. To find the range, we have to arrange the data in the increasing order of value, so it is arranged as, 5, 6, 6, 7, 9, 9, 9. Now, we have to find the difference between the maximum and the least value as, 9 - 5 = 4 So the range of the given data set is 4.
