Step 1

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

$\frac{5 + 2 + 6 + 0 + 1 + 1 + 3 + 4 + 3 + 6 - 1}{11}$

Step 2

Step 2.1

Add $5$ and $2$ .

$\frac{7 + 6 + 0 + 1 + 1 + 3 + 4 + 3 + 6 - 1}{11}$

Step 2.2

Add $7$ and $6$ .

$\frac{13 + 0 + 1 + 1 + 3 + 4 + 3 + 6 - 1}{11}$

Step 2.3

Add $13$ and $0$ .

$\frac{13 + 1 + 1 + 3 + 4 + 3 + 6 - 1}{11}$

Step 2.4

Add $13$ and $1$ .

$\frac{14 + 1 + 3 + 4 + 3 + 6 - 1}{11}$

Step 2.5

Add $14$ and $1$ .

$\frac{15 + 3 + 4 + 3 + 6 - 1}{11}$

Step 2.6

Add $15$ and $3$ .

$\frac{18 + 4 + 3 + 6 - 1}{11}$

Step 2.7

Add $18$ and $4$ .

$\frac{22 + 3 + 6 - 1}{11}$

Step 2.8

Add $22$ and $3$ .

$\frac{25 + 6 - 1}{11}$

Step 2.9

Add $25$ and $6$ .

$\frac{31 - 1}{11}$

Step 2.10

Subtract $1$ from $31$ .

$\frac{30}{11}$

Step 3

Divide.

$2.\overline{72}$

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.
