What is the mean of 8,7,5,7,4,7,6,7,8,8,8,6

6,75

Step-by-step explanation:

It's necessary the addition of all numbers, divided between the number of the numbers. It means: 8 + 7 + 5 + 7 + 4 + 7 + 6 + 7 + 8 + 8 + 8 + 6 = 81, then we'll divide 81 between 12 (because there are 12 numbers), and the result is 6,75

Mean = ∑numbers/n numbers

6.75

Step-by-step explanation:

1. Add all the numbers (81)
