Step 1

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

$\frac{56 + 61 + 64 + 48 + 63 + 60 + 57 + 65 + 64 + 60 + 65 + 68 + 48 + 64 + 59 + 59}{16}$

Step 2

Simplify the numerator.

Add $56$ and $61$ .

$\frac{117 + 64 + 48 + 63 + 60 + 57 + 65 + 64 + 60 + 65 + 68 + 48 + 64 + 59 + 59}{16}$

Add $117$ and $64$ .

$\frac{181 + 48 + 63 + 60 + 57 + 65 + 64 + 60 + 65 + 68 + 48 + 64 + 59 + 59}{16}$

Add $181$ and $48$ .

$\frac{229 + 63 + 60 + 57 + 65 + 64 + 60 + 65 + 68 + 48 + 64 + 59 + 59}{16}$

Add $229$ and $63$ .

$\frac{292 + 60 + 57 + 65 + 64 + 60 + 65 + 68 + 48 + 64 + 59 + 59}{16}$

Add $292$ and $60$ .

$\frac{352 + 57 + 65 + 64 + 60 + 65 + 68 + 48 + 64 + 59 + 59}{16}$

Add $352$ and $57$ .

$\frac{409 + 65 + 64 + 60 + 65 + 68 + 48 + 64 + 59 + 59}{16}$

Add $409$ and $65$ .

$\frac{474 + 64 + 60 + 65 + 68 + 48 + 64 + 59 + 59}{16}$

Add $474$ and $64$ .

$\frac{538 + 60 + 65 + 68 + 48 + 64 + 59 + 59}{16}$

Add $538$ and $60$ .

$\frac{598 + 65 + 68 + 48 + 64 + 59 + 59}{16}$

Add $598$ and $65$ .

$\frac{663 + 68 + 48 + 64 + 59 + 59}{16}$

Add $663$ and $68$ .

$\frac{731 + 48 + 64 + 59 + 59}{16}$

Add $731$ and $48$ .

$\frac{779 + 64 + 59 + 59}{16}$

Add $779$ and $64$ .

$\frac{843 + 59 + 59}{16}$

Add $843$ and $59$ .

$\frac{902 + 59}{16}$

Add $902$ and $59$ .

$\frac{961}{16}$

Step 3

Divide.

$60.0625$

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.

$60.1$
