Mean of 5, 7, 9, 11 is what value?

Explanation:
Mean is found by adding all the values and dividing by how many values there are. Add 5 + 7 + 9 + 11 to get 32, and there are four numbers, so 32 ÷ 4 = 8. So the average is 8. For an even count, the mean also matches the midpoint of the two middle numbers, (7 + 9) ÷ 2 = 8, which confirms the result.
