$2.23$ , $2.42$ , $2.44$ , $10.04$ , $2.51$ , $2.39$ , $2.04$

Step 1

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

$\frac{2.23 + 2.42 + 2.44 + 10.04 + 2.51 + 2.39 + 2.04}{7}$

Step 2

Step 2.1

Add $2.23$ and $2.42$ .

$\frac{4.65 + 2.44 + 10.04 + 2.51 + 2.39 + 2.04}{7}$

Step 2.2

Add $4.65$ and $2.44$ .

$\frac{7.09 + 10.04 + 2.51 + 2.39 + 2.04}{7}$

Step 2.3

Add $7.09$ and $10.04$ .

$\frac{17.13 + 2.51 + 2.39 + 2.04}{7}$

Step 2.4

Add $17.13$ and $2.51$ .

$\frac{19.64 + 2.39 + 2.04}{7}$

Step 2.5

Add $19.64$ and $2.39$ .

$\frac{22.03 + 2.04}{7}$

Step 2.6

Add $22.03$ and $2.04$ .

$\frac{24.07}{7}$

Step 3

Divide $24.07$ by $7$ .

$3.43857142$

Step 4

Divide.

$3.43857142$

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.
