Full solution

Q. What is the mean?

\newline

2, 6, 3, 5, 2, 0

\newline

_____

Add Numbers to Find Sum: Add all the numbers in the data set together to find the sum. $2 + 6 + 3 + 5 + 2 + 0 = 18$
Count Values: Count the number of values in the data set. $\newline$ There are $6$ numbers in the data set.
Calculate Mean: Divide the sum of the data set by the number of values to find the mean. $\newline$ Mean = $\frac{\text{Sum of values}}{\text{Number of values}}$ $\newline$ Mean = $\frac{18}{6}$ $\newline$ Mean = $3$
