What is the median of the data set 3, 5, 7, 9, 100?

Explanation:
The median is the middle value of a data set when the numbers are arranged from smallest to largest. With five numbers, the middle position is the third one. Ordering the data gives 3, 5, 7, 9, 100, and the third value is 7. So the median is 7. Notice how the outlier 100 doesn’t affect the median in this case because the middle value is determined by the central item in the ordered list, not by extreme values.
