Step 1

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

$\frac{6.8 + 9.3 + 3.8 + 3.3 + 7.2 + 6.6 + 4.8 + 9.3 + 1.8 + 1.9 + 4.4}{11}$

Step 2

Simplify the numerator.

Add

$6.8$ and

$9.3$ .

$\frac{16.1 + 3.8 + 3.3 + 7.2 + 6.6 + 4.8 + 9.3 + 1.8 + 1.9 + 4.4}{11}$

Add

$16.1$ and

$3.8$ .

$\frac{19.9 + 3.3 + 7.2 + 6.6 + 4.8 + 9.3 + 1.8 + 1.9 + 4.4}{11}$

Add

$19.9$ and

$3.3$ .

$\frac{23.2 + 7.2 + 6.6 + 4.8 + 9.3 + 1.8 + 1.9 + 4.4}{11}$

Add

$23.2$ and

$7.2$ .

$\frac{30.4 + 6.6 + 4.8 + 9.3 + 1.8 + 1.9 + 4.4}{11}$

Add

$30.4$ and

$6.6$ .

$\frac{37 + 4.8 + 9.3 + 1.8 + 1.9 + 4.4}{11}$

Add

$37$ and

$4.8$ .

$\frac{41.8 + 9.3 + 1.8 + 1.9 + 4.4}{11}$

Add

$41.8$ and

$9.3$ .

$\frac{51.1 + 1.8 + 1.9 + 4.4}{11}$

Add

$51.1$ and

$1.8$ .

$\frac{52.9 + 1.9 + 4.4}{11}$

Add

$52.9$ and

$1.9$ .

$\frac{54.8 + 4.4}{11}$

Add

$54.8$ and

$4.4$ .

$\frac{59.2}{11}$

Step 3

Divide

$59.2$ by

$11$ .

$5.3\overline{81}$

Step 4

Divide.

$5.3\overline{81}$

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.
