$- 5.3$ , $- 5.\overline{3}$

Step 1

The mean of a set of numbers is the sum divided by the number of terms.

$\frac{- 5.3 - 5.\overline{3}}{2}$

Step 2

Subtract $5.\overline{3}$ from $- 5.3$ .

$\frac{- 10.6\overline{3}}{2}$

Step 3

Divide $- 10.6\overline{3}$ by $2$ .

$- 5.31\overline{6}$

Step 4

The mean should be rounded to one more decimal place than the original data. If the original data were mixed, round to one decimal place more than the least precise.

$- 5.32$
