$5.6$ , $10.8$ , $18.2$ , $32.7$ , $12.8$ , $8.7$ , $10.8$ , $16.7$

Step 1

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

$\frac{5.6 + 10.8 + 18.2 + 32.7 + 12.8 + 8.7 + 10.8 + 16.7}{8}$

Step 2

Step 2.1

Add $5.6$ and $10.8$ .

$\frac{16.4 + 18.2 + 32.7 + 12.8 + 8.7 + 10.8 + 16.7}{8}$

Step 2.2

Add $16.4$ and $18.2$ .

$\frac{34.6 + 32.7 + 12.8 + 8.7 + 10.8 + 16.7}{8}$

Step 2.3

Add $34.6$ and $32.7$ .

$\frac{67.3 + 12.8 + 8.7 + 10.8 + 16.7}{8}$

Step 2.4

Add $67.3$ and $12.8$ .

$\frac{80.1 + 8.7 + 10.8 + 16.7}{8}$

Step 2.5

Add $80.1$ and $8.7$ .

$\frac{88.8 + 10.8 + 16.7}{8}$

Step 2.6

Add $88.8$ and $10.8$ .

$\frac{99.6 + 16.7}{8}$

Step 2.7

Add $99.6$ and $16.7$ .

$\frac{116.3}{8}$

Step 3

Divide $116.3$ by $8$ .

$14.5375$

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.

$14.54$
