$9.6$ , $6.4$ , $8.7$ , $4.5$ , $2.6$ , $1.5$ , $7.4$ , $6.7$ , $9.8$ , $6.8$ , $3.4$

Step 1

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

$\frac{9.6 + 6.4 + 8.7 + 4.5 + 2.6 + 1.5 + 7.4 + 6.7 + 9.8 + 6.8 + 3.4}{11}$

Step 2.1

Add $9.6$ and $6.4$ .

$\frac{16 + 8.7 + 4.5 + 2.6 + 1.5 + 7.4 + 6.7 + 9.8 + 6.8 + 3.4}{11}$

Step 2.2

Add $16$ and $8.7$ .

$\frac{24.7 + 4.5 + 2.6 + 1.5 + 7.4 + 6.7 + 9.8 + 6.8 + 3.4}{11}$

Step 2.3

Add $24.7$ and $4.5$ .

$\frac{29.2 + 2.6 + 1.5 + 7.4 + 6.7 + 9.8 + 6.8 + 3.4}{11}$

Step 2.4

Add $29.2$ and $2.6$ .

$\frac{31.8 + 1.5 + 7.4 + 6.7 + 9.8 + 6.8 + 3.4}{11}$

Step 2.5

Add $31.8$ and $1.5$ .

$\frac{33.3 + 7.4 + 6.7 + 9.8 + 6.8 + 3.4}{11}$

Step 2.6

Add $33.3$ and $7.4$ .

$\frac{40.7 + 6.7 + 9.8 + 6.8 + 3.4}{11}$

Step 2.7

Add $40.7$ and $6.7$ .

$\frac{47.4 + 9.8 + 6.8 + 3.4}{11}$

Step 2.8

Add $47.4$ and $9.8$ .

$\frac{57.2 + 6.8 + 3.4}{11}$

Step 2.9

Add $57.2$ and $6.8$ .

$\frac{64 + 3.4}{11}$

Step 2.10

Add $64$ and $3.4$ .

$\frac{67.4}{11}$

Step 3

Divide $67.4$ by $11$ .

$6.1\overline{27}$

Step 4

Divide.

$6.1\overline{27}$

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.
