$5.5$ , $7.6$ , $3.7$ , $2.4$ , $8.9$ , $4.9$ , $5.2$ , $7.8$ , $3.4$ , $1.9$ , $5.9$

Step 1

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

$\frac{5.5 + 7.6 + 3.7 + 2.4 + 8.9 + 4.9 + 5.2 + 7.8 + 3.4 + 1.9 + 5.9}{11}$

Step 2

Simplify the numerator.

Step 2.1

Add $5.5$ and $7.6$ .

$\frac{13.1 + 3.7 + 2.4 + 8.9 + 4.9 + 5.2 + 7.8 + 3.4 + 1.9 + 5.9}{11}$

Step 2.2

Add $13.1$ and $3.7$ .

$\frac{16.8 + 2.4 + 8.9 + 4.9 + 5.2 + 7.8 + 3.4 + 1.9 + 5.9}{11}$

Step 2.3

Add $16.8$ and $2.4$ .

$\frac{19.2 + 8.9 + 4.9 + 5.2 + 7.8 + 3.4 + 1.9 + 5.9}{11}$

Step 2.4

Add $19.2$ and $8.9$ .

$\frac{28.1 + 4.9 + 5.2 + 7.8 + 3.4 + 1.9 + 5.9}{11}$

Step 2.5

Add $28.1$ and $4.9$ .

$\frac{33 + 5.2 + 7.8 + 3.4 + 1.9 + 5.9}{11}$

Step 2.6

Add $33$ and $5.2$ .

$\frac{38.2 + 7.8 + 3.4 + 1.9 + 5.9}{11}$

Step 2.7

Add $38.2$ and $7.8$ .

$\frac{46 + 3.4 + 1.9 + 5.9}{11}$

Step 2.8

Add $46$ and $3.4$ .

$\frac{49.4 + 1.9 + 5.9}{11}$

Step 2.9

Add $49.4$ and $1.9$ .

$\frac{51.3 + 5.9}{11}$

Step 2.10

Add $51.3$ and $5.9$ .

$\frac{57.2}{11}$

Step 3

Divide $57.2$ by $11$ .

$5.2$

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.

$5.2$
