What is the median of the data set {2, 5, 5, 7, 9}?

Explanation:
The median is the middle value of a data set when the numbers are arranged from smallest to largest. Arrange the data: 2, 5, 5, 7, 9. With five numbers, the middle position is the third one, which is 5, so the median is 5. (If there were an even number of data points, you would average the two middle values to find the median.)
