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

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

Substitute the values of maximum $18$ and minimum $3$ into the equation.

$Mid-Range = \frac{18 + 3}{2}$

Add $18$ and $3$ .

$Mid-Range = \frac{21}{2}$

Convert $\frac{21}{2}$ to decimal.

$Mid-Range = 10.5$
