Step 1

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

$\frac{0.7 + 0.8 + 1 + 1.1 + 1.1 + 1.4 + 0.7 + 1.2 + 1.6}{9}$

Step 2

Simplify the numerator.

Add

$0.7$ and

$0.8$ .

$\frac{1.5 + 1 + 1.1 + 1.1 + 1.4 + 0.7 + 1.2 + 1.6}{9}$

Add

$1.5$ and

$1$ .

$\frac{2.5 + 1.1 + 1.1 + 1.4 + 0.7 + 1.2 + 1.6}{9}$

Add

$2.5$ and

$1.1$ .

$\frac{3.6 + 1.1 + 1.4 + 0.7 + 1.2 + 1.6}{9}$

Add

$3.6$ and

$1.1$ .

$\frac{4.7 + 1.4 + 0.7 + 1.2 + 1.6}{9}$

Add

$4.7$ and

$1.4$ .

$\frac{6.1 + 0.7 + 1.2 + 1.6}{9}$

Add

$6.1$ and

$0.7$ .

$\frac{6.8 + 1.2 + 1.6}{9}$

Add

$6.8$ and

$1.2$ .

$\frac{8 + 1.6}{9}$

Add

$8$ and

$1.6$ .

$\frac{9.6}{9}$

Step 3

Divide

$9.6$ by

$9$ .

$1.0\overline{6}$

Step 4

Divide.

$1.0\overline{6}$

Step 5

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.

$1.1$
