To find the mean of a set of data you must add the data together then divide the sum by the number of data in the set.
Step 1: Adding together the data
6 + (-10) + 6 + (-6) + 5 + 4 + (-8) = -3
Step 2: Count how many number there are in the data set
There are 7 numbers in this data set
Step 3: Divide the sum of the data (-3) by the number of data in the set (7)
-3 ÷ 7 =
OR
-3 ÷ 7 ≈ -0.43
The mean of this data set is
OR -0.43
Hope this helped!
