Multiple Choice

In the data set {2, 4, 4, 6, 8}, what is the median?

The median is the middle value when data are ordered from smallest to largest. Arrange the set: 2, 4, 4, 6, 8. With five numbers, the middle one is the third item, which is 4. So the median is 4. The other options don’t fit because 2 is the smallest, 6 is the second largest, and 5 isn’t even a data value (median would be the average of two middle numbers only if there were an even number of values).
