If the values 2, 4, 6, and 8 are in a data set, what is the mean?

Explanation:
The mean (average) is found by adding all the numbers and dividing by how many numbers there are. Here, 2 + 4 + 6 + 8 equals 20, and there are 4 values. So the mean is 20 ÷ 4 = 5. The mean is 5 because it’s the total sum distributed evenly across the four data points. If the total were 12, 16, or 24, the mean would be 3, 4, or 6 respectively—but the actual sum is 20, giving a mean of 5.
