Step 1

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

$\frac{0 + 0.04 + 0.12 + 0.18 + 0.48 + 1.1 + 1.8 + 0.84 + 0.4}{9}$

Step 2

Step 2.1

Add $0$ and $0.04$ .

$\frac{0.04 + 0.12 + 0.18 + 0.48 + 1.1 + 1.8 + 0.84 + 0.4}{9}$

Step 2.2

Add $0.04$ and $0.12$ .

$\frac{0.16 + 0.18 + 0.48 + 1.1 + 1.8 + 0.84 + 0.4}{9}$

Step 2.3

Add $0.16$ and $0.18$ .

$\frac{0.34 + 0.48 + 1.1 + 1.8 + 0.84 + 0.4}{9}$

Step 2.4

Add $0.34$ and $0.48$ .

$\frac{0.82 + 1.1 + 1.8 + 0.84 + 0.4}{9}$

Step 2.5

Add $0.82$ and $1.1$ .

$\frac{1.92 + 1.8 + 0.84 + 0.4}{9}$

Step 2.6

Add $1.92$ and $1.8$ .

$\frac{3.72 + 0.84 + 0.4}{9}$

Step 2.7

Add $3.72$ and $0.84$ .

$\frac{4.56 + 0.4}{9}$

Step 2.8

Add $4.56$ and $0.4$ .

$\frac{4.96}{9}$

Step 3

Divide $4.96$ by $9$ .

$0.55\overline{1}$

Step 4

Divide.

$0.55\overline{1}$

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.

$0.551$
