Question

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

Answer 1

6,75

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

Answer 2

6.75

Explanation:

1. Add all the numbers (81)

2. Divide by how many numbers there is (12)

3. 81 ÷ 12 = 6.75
