$37.6$ , $36.8$ , $34.6$ , $27$ , $15.3$ , $13.9$ , $12.5$ , $10.9$ , $9.9$ , $7.6$

Step 1

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

$\frac{37.6 + 36.8 + 34.6 + 27 + 15.3 + 13.9 + 12.5 + 10.9 + 9.9 + 7.6}{10}$

Step 2

Step 2.1

Add $37.6$ and $36.8$ .

$\frac{74.4 + 34.6 + 27 + 15.3 + 13.9 + 12.5 + 10.9 + 9.9 + 7.6}{10}$

Step 2.2

Add $74.4$ and $34.6$ .

$\frac{109 + 27 + 15.3 + 13.9 + 12.5 + 10.9 + 9.9 + 7.6}{10}$

Step 2.3

Add $109$ and $27$ .

$\frac{136 + 15.3 + 13.9 + 12.5 + 10.9 + 9.9 + 7.6}{10}$

Step 2.4

Add $136$ and $15.3$ .

$\frac{151.3 + 13.9 + 12.5 + 10.9 + 9.9 + 7.6}{10}$

Step 2.5

Add $151.3$ and $13.9$ .

$\frac{165.2 + 12.5 + 10.9 + 9.9 + 7.6}{10}$

Step 2.6

Add $165.2$ and $12.5$ .

$\frac{177.7 + 10.9 + 9.9 + 7.6}{10}$

Step 2.7

Add $177.7$ and $10.9$ .

$\frac{188.6 + 9.9 + 7.6}{10}$

Step 2.8

Add $188.6$ and $9.9$ .

$\frac{198.5 + 7.6}{10}$

Step 2.9

Add $198.5$ and $7.6$ .

$\frac{206.1}{10}$

Step 3

Divide $206.1$ by $10$ .

$20.61$

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.

$20.6$
