#### Answer

The midrange is 4.

#### Work Step by Step

To find the midrange of a set of data, we must add the smallest value in the data set and the largest number in the data set. Then we divide the sum by 2.
The smallest value is 1. The largest value is 7.
The midrange is $\frac{1 + 7}{2}$ = $\frac{8}{2}$ = 4
