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 $21$ and minimum $14$ into the equation.

$Mid-Range = \frac{21 + 14}{2}$

Step 3

Add $21$ and $14$ .

$Mid-Range = \frac{35}{2}$

Step 4

Convert $\frac{35}{2}$ to decimal.

$Mid-Range = 17.5$
