Find the Sample Standard Deviation 1 , 9 , 4 , 12 , 13 , 13

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

Simplify the numerator.

Cancel the common factor of ${\displaystyle 52}$ and ${\displaystyle 6}$.

Divide.

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.
