In a recent survey, 8 college graduates were each asked for the number of hours they work each week. Here is a list of the responses.

Question

38, 39, 53, 42, 53, 43, 37, 44
Find the range of the data set.

Answer 1

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

First, we identify the maximum and minimum values from the responses:

• Maximum: 53
• Minimum: 37

Now, calculate the range:

\[ \text{Range} = \text{Maximum} - \text{Minimum} = 53 - 37 = 16 \]

Thus, the range of the data set is 16.
