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

To find the range of a set of data, you subtract the minimum value from the maximum value.

From the given data set:
9, 4.5, 8, 6, 9.5, 5, 6.5, 14, 4

1. Identify the maximum value:
- The maximum value is 14.

2. Identify the minimum value:
- The minimum value is 4.

3. Calculate the range:
\[
\text{Range} = \text{Maximum} - \text{Minimum} = 14 - 4 = 10
\]

So, the value of the range for this set of data is \( \boxed{10} \).
