Find the range of the data set 3, 7, 7, 7, 9.

Explanation:
The range is the difference between the largest and smallest values in a data set. Here, the smallest value is 3 and the largest is 9, so the range is 9 − 3 = 6. This shows how far the data spread from the minimum up to the maximum. The other numbers don’t fit because they would reflect smaller spreads, not the overall distance from 3 to 9.
