Step 1

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

$\frac{10 + 14 + 14 + 23 + 38 + 45 + 50 + 60 + 68}{9}$

Step 2.1

Add $10$ and $14$ .

$\frac{24 + 14 + 23 + 38 + 45 + 50 + 60 + 68}{9}$

Step 2.2

Add $24$ and $14$ .

$\frac{38 + 23 + 38 + 45 + 50 + 60 + 68}{9}$

Step 2.3

Add $38$ and $23$ .

$\frac{61 + 38 + 45 + 50 + 60 + 68}{9}$

Step 2.4

Add $61$ and $38$ .

$\frac{99 + 45 + 50 + 60 + 68}{9}$

Step 2.5

Add $99$ and $45$ .

$\frac{144 + 50 + 60 + 68}{9}$

Step 2.6

Add $144$ and $50$ .

$\frac{194 + 60 + 68}{9}$

Step 2.7

Add $194$ and $60$ .

$\frac{254 + 68}{9}$

Step 2.8

Add $254$ and $68$ .

$\frac{322}{9}$

Step 3

Divide.

$35.\overline{7}$

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.
