Add up all data values to get the sum
Count the number of values in your data set
Divide the sum by the count
Calculate the mean of 2,3,4,5,8,8,12
Step 1: Add all the numbers together, to find the sum
2 + 3 + 4 + 5 + 8 + 8 + 12 = 42
Step 2: Count the number of values in your data set
There are 7 numbers
Step 3: Divide the sum by the count
42 ÷ 7 = 6
