Step 1

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

$\frac{48 + 65 + 57 + 54 + 61 + 57 + 52 + 61 + 57}{9}$

Step 2.1

Add $48$ and $65$ .

$\frac{113 + 57 + 54 + 61 + 57 + 52 + 61 + 57}{9}$

Step 2.2

Add $113$ and $57$ .

$\frac{170 + 54 + 61 + 57 + 52 + 61 + 57}{9}$

Step 2.3

Add $170$ and $54$ .

$\frac{224 + 61 + 57 + 52 + 61 + 57}{9}$

Step 2.4

Add $224$ and $61$ .

$\frac{285 + 57 + 52 + 61 + 57}{9}$

Step 2.5

Add $285$ and $57$ .

$\frac{342 + 52 + 61 + 57}{9}$

Step 2.6

Add $342$ and $52$ .

$\frac{394 + 61 + 57}{9}$

Step 2.7

Add $394$ and $61$ .

$\frac{455 + 57}{9}$

Step 2.8

Add $455$ and $57$ .

$\frac{512}{9}$

Step 3

Divide.

$56.\overline{8}$

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.
