How do you determine the range of the data set: 1, 4, 7, 8, 10?

To determine the range of a data set, you need to follow a straightforward process. The range is calculated by subtracting the smallest value in the set from the largest value.

In the set provided (1, 4, 7, 8, 10), the smallest value is 1, and the largest value is 10.

When you perform the calculation:

Range = Largest value - Smallest value

Range = 10 - 1 = 9

This computation leads to a range of 9, meaning that the spread or difference between the highest and lowest values in the data set is 9.

Thus, the correct answer reflects the proper calculation and understanding of how to find the range in a data set.
