Find the Mean 16 , 19 , 25 , 32 , 38 , 40

$16$ , $19$ , $25$ , $32$ , $38$ , $40$

Step 1

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

$\frac{16 + 19 + 25 + 32 + 38 + 40}{6}$

Step 2

Simplify the numerator.

Add $16$ and $19$ .

$\frac{35 + 25 + 32 + 38 + 40}{6}$

Add $35$ and $25$ .

$\frac{60 + 32 + 38 + 40}{6}$

Add $60$ and $32$ .

$\frac{92 + 38 + 40}{6}$

Add $92$ and $38$ .

$\frac{130 + 40}{6}$

Add $130$ and $40$ .

$\frac{170}{6}$

Step 3

Cancel the common factor of $170$ and $6$ .

Factor $2$ out of $170$ .

$\frac{2 (85)}{6}$

Cancel the common factors.

Factor $2$ out of $6$ .

$\frac{2 \cdot 85}{2 \cdot 3}$

Cancel the common factor.

$\frac{2 \cdot 85}{2 \cdot 3}$

Rewrite the expression.

$\frac{85}{3}$

Step 4

Divide.

$28.\overline{3}$

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.

$28.3$
