Step 1

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

$\frac{14 + 2 + 15 + 15 + 2 + 1 + 5 + 7 + 11 + 6 + 2}{11}$

Step 2.1

Add $14$ and $2$ .

$\frac{16 + 15 + 15 + 2 + 1 + 5 + 7 + 11 + 6 + 2}{11}$

Step 2.2

Add $16$ and $15$ .

$\frac{31 + 15 + 2 + 1 + 5 + 7 + 11 + 6 + 2}{11}$

Step 2.3

Add $31$ and $15$ .

$\frac{46 + 2 + 1 + 5 + 7 + 11 + 6 + 2}{11}$

Step 2.4

Add $46$ and $2$ .

$\frac{48 + 1 + 5 + 7 + 11 + 6 + 2}{11}$

Step 2.5

Add $48$ and $1$ .

$\frac{49 + 5 + 7 + 11 + 6 + 2}{11}$

Step 2.6

Add $49$ and $5$ .

$\frac{54 + 7 + 11 + 6 + 2}{11}$

Step 2.7

Add $54$ and $7$ .

$\frac{61 + 11 + 6 + 2}{11}$

Step 2.8

Add $61$ and $11$ .

$\frac{72 + 6 + 2}{11}$

Step 2.9

Add $72$ and $6$ .

$\frac{78 + 2}{11}$

Step 2.10

Add $78$ and $2$ .

$\frac{80}{11}$

Step 3

Divide.

$7.\overline{27}$

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.
