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 $28$ and minimum $11$ into the equation.

$Mid-Range = \frac{28 + 11}{2}$

Step 3

Add $28$ and $11$ .

$Mid-Range = \frac{39}{2}$

Step 4

Convert $\frac{39}{2}$ to decimal.

$Mid-Range = 19.5$
