Find the Mean 0.6 , 0.7 , 0.9 , 0.8 , 0.8 , 1.3 , 0.6 , 1.1 , 1.5

$0.6$ , $0.7$ , $0.9$ , $0.8$ , $0.8$ , $1.3$ , $0.6$ , $1.1$ , $1.5$

Step 1

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

$\frac{0.6 + 0.7 + 0.9 + 0.8 + 0.8 + 1.3 + 0.6 + 1.1 + 1.5}{9}$

Step 2

Simplify the numerator.

Add $0.6$ and $0.7$ .

$\frac{1.3 + 0.9 + 0.8 + 0.8 + 1.3 + 0.6 + 1.1 + 1.5}{9}$

Add $1.3$ and $0.9$ .

$\frac{2.2 + 0.8 + 0.8 + 1.3 + 0.6 + 1.1 + 1.5}{9}$

Add $2.2$ and $0.8$ .

$\frac{3 + 0.8 + 1.3 + 0.6 + 1.1 + 1.5}{9}$

Add $3$ and $0.8$ .

$\frac{3.8 + 1.3 + 0.6 + 1.1 + 1.5}{9}$

Add $3.8$ and $1.3$ .

$\frac{5.1 + 0.6 + 1.1 + 1.5}{9}$

Add $5.1$ and $0.6$ .

$\frac{5.7 + 1.1 + 1.5}{9}$

Add $5.7$ and $1.1$ .

$\frac{6.8 + 1.5}{9}$

Add $6.8$ and $1.5$ .

$\frac{8.3}{9}$

Step 3

Divide $8.3$ by $9$ .

$0.9\overline{2}$

Step 4

Divide.

$0.9\overline{2}$

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.

$0.92$
