$0.957$ , $0.912$ , $0.925$ , $0.886$ , $0.92$ , $0.958$ , $0.915$ , $0.914$ , $0.947$ , $0.939$ , $0.84$

Step 1

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

$\frac{0.957 + 0.912 + 0.925 + 0.886 + 0.92 + 0.958 + 0.915 + 0.914 + 0.947 + 0.939 + 0.84}{11}$

Step 2.2

Add $1.869$ and $0.925$ .

$\frac{2.794 + 0.886 + 0.92 + 0.958 + 0.915 + 0.914 + 0.947 + 0.939 + 0.84}{11}$

Step 2.3

Add $2.794$ and $0.886$ .

$\frac{3.68 + 0.92 + 0.958 + 0.915 + 0.914 + 0.947 + 0.939 + 0.84}{11}$

Step 2.4

Add $3.68$ and $0.92$ .

$\frac{4.6 + 0.958 + 0.915 + 0.914 + 0.947 + 0.939 + 0.84}{11}$

Step 2.5

Add $4.6$ and $0.958$ .

$\frac{5.558 + 0.915 + 0.914 + 0.947 + 0.939 + 0.84}{11}$

Step 2.6

Add $5.558$ and $0.915$ .

$\frac{6.473 + 0.914 + 0.947 + 0.939 + 0.84}{11}$

Step 2.7

Add $6.473$ and $0.914$ .

$\frac{7.387 + 0.947 + 0.939 + 0.84}{11}$

Step 2.8

Add $7.387$ and $0.947$ .

$\frac{8.334 + 0.939 + 0.84}{11}$

Step 2.9

Add $8.334$ and $0.939$ .

$\frac{9.273 + 0.84}{11}$

Step 2.10

Add $9.273$ and $0.84$ .

$\frac{10.113}{11}$

Step 3

Divide $10.113$ by $11$ .

$0.919\overline{36}$

Step 4

Divide.

$0.919\overline{36}$

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.

$0.919$
