Question

The number of hours a student spent studying each week for 9 weeks is shown.

9, 4.5, 8, 6, 9.5, 5, 6.5, 14, 4

What is the value of the range for this set of data?

4
14
6.5
10

Answer 1

D

Explanation:

To find the range, we need to first find the difference between the highest and lowest values in the data set.

The highest value is 14, and the lowest value is 4.

Range = Highest value - Lowest value = 14 - 4 = 10

Therefore, the value of the range for this set of data is 10. Option D is correct.
