Mean- the average of a data set
To find the mean you add all numbers and then divide by the amount of numbers in the data set.
Example: Find the mean of 6, 7, and 11.
6 + 7 + 11 = 24
Divide the sum by the amount of numbers in the data set. There are 3 numbers in the data set.
24/3 = 8
The mean is 8.
