How to Find the Mean

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

So the mean is 6
