$62$ ,

$63$ ,

$64$ ,

$68$

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

$68$ and minimum

$62$ into the equation.

$Mid-Range = \frac{68 + 62}{2}$

Step 3

Cancel the common factor of

$68 + 62$ and

$2$ .

Step 3.1

Factor

$2$ out of

$68$ .

$Mid-Range = \frac{2 \cdot 34 + 62}{2}$

Step 3.2

Factor

$2$ out of

$62$ .

$Mid-Range = \frac{2 \cdot 34 + 2 \cdot 31}{2}$

Step 3.3

Factor

$2$ out of

$2 \cdot 34 + 2 \cdot 31$ .

$Mid-Range = \frac{2 \cdot (34 + 31)}{2}$

Step 3.4

Cancel the common factors.

Step 3.4.1

Factor

$2$ out of

$2$ .

$Mid-Range = \frac{2 \cdot (34 + 31)}{2 (1)}$

Step 3.4.2

Cancel the common factor.

$Mid-Range = \frac{2 \cdot (34 + 31)}{2 \cdot 1}$

Step 3.4.3

Rewrite the expression.

$Mid-Range = \frac{34 + 31}{1}$

Step 3.4.4

Divide

$34 + 31$ by

$1$ .

$Mid-Range = 34 + 31$

Step 4

Add

$34$ and

$31$ .

$Mid-Range = 65$

Step 5

Convert

$65$ to decimal.

$Mid-Range = 65$
