Step 1

The mid-range or mid-extreme of a set of statistical data values is the average of the maximum and minimum values.

$Mid-Range = \frac{Maximum + Minimum}{2}$

Step 2

Substitute the values of maximum $151$ and minimum $118$ into the equation.

$Mid-Range = \frac{151 + 118}{2}$

Step 3

Add $151$ and $118$ .

$Mid-Range = \frac{269}{2}$

Step 4

Convert $\frac{269}{2}$ to decimal.

$Mid-Range = 134.5$
