What is the median of a data set?
AThe most common value
BThe average of them all
CThe largest minus smallest
DThe middle ordered value
Answer & Solution
Correct answer: D. The middle ordered value
1. Sort the data into ascending or descending order first.
2. The median is then the value that sits in the middle of that sorted list.
3. If the middle falls between two values, take the average of those two.
4. The most common value is the mode, which is a different measure.
