What is the mean of the data set [2, 5, 7, 3, 9]?

Explanation:
You're being asked to find the mean, or average, of the numbers. Add them up: 2 + 5 + 7 + 3 + 9 = 26. There are 5 numbers, so divide the total by 5: 26 ÷ 5 = 5.2. So the mean is 5.2. This value is the balance point that represents the average of all observations.
