What is the median of the data set: 3, 7, 7, 9, 12?

The median is the middle value of a data set when the numbers are arranged from smallest to largest. With five numbers, the median is the third value in that ordered list. The data are already sorted as 3, 7, 7, 9, 12, so the third value is 7. Therefore, the median is 7. If there were an even number of values, you’d average the two central numbers.
