What is the mean of the data set 2, 4, 6, 6, 8?

Explanation:
Mean is the average value of a set, found by adding all the numbers and dividing by how many numbers there are. For 2, 4, 6, 6, 8, the sum is 2 + 4 + 6 + 6 + 8 = 26. There are 5 numbers, so the mean is 26 ÷ 5 = 5.2. This matches the value 5.2. The other possible means would come from totals of 25, 27, or 24, which don’t equal the actual total, so they aren’t correct.
