Step 1

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

$\frac{7.64 + 7.45 + 7.47 + 7.5 + 7.68 + 7.93 + 7.45 + 7.1 + 7.56 + 7.47 + 7.52 + 7.47}{12}$

Step 2

Simplify the numerator.

Add

$7.64$ and

$7.45$ .

$\frac{15.09 + 7.47 + 7.5 + 7.68 + 7.93 + 7.45 + 7.1 + 7.56 + 7.47 + 7.52 + 7.47}{12}$

Add

$15.09$ and

$7.47$ .

$\frac{22.56 + 7.5 + 7.68 + 7.93 + 7.45 + 7.1 + 7.56 + 7.47 + 7.52 + 7.47}{12}$

Add

$22.56$ and

$7.5$ .

$\frac{30.06 + 7.68 + 7.93 + 7.45 + 7.1 + 7.56 + 7.47 + 7.52 + 7.47}{12}$

Add

$30.06$ and

$7.68$ .

$\frac{37.74 + 7.93 + 7.45 + 7.1 + 7.56 + 7.47 + 7.52 + 7.47}{12}$

Add

$37.74$ and

$7.93$ .

$\frac{45.67 + 7.45 + 7.1 + 7.56 + 7.47 + 7.52 + 7.47}{12}$

Add

$45.67$ and

$7.45$ .

$\frac{53.12 + 7.1 + 7.56 + 7.47 + 7.52 + 7.47}{12}$

Add

$53.12$ and

$7.1$ .

$\frac{60.22 + 7.56 + 7.47 + 7.52 + 7.47}{12}$

Add

$60.22$ and

$7.56$ .

$\frac{67.78 + 7.47 + 7.52 + 7.47}{12}$

Add

$67.78$ and

$7.47$ .

$\frac{75.25 + 7.52 + 7.47}{12}$

Add

$75.25$ and

$7.52$ .

$\frac{82.77 + 7.47}{12}$

Add

$82.77$ and

$7.47$ .

$\frac{90.24}{12}$

Step 3

Divide

$90.24$ by

$12$ .

$7.52$

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.
