Why Do We Need Both Mean and Median to Understand Data?

Quick fact

A single very high income can pull the mean far above what most people earn, while the median (the middle value) stays almost the same—showing that the mean isn't always the best representation of the 'typical' person.

Why this is interesting

Imagine a neighbourhood where the average salary is reported as $1 million a year. Would you believe it? Probably not, and the reason why lies in the difference between the mean and the median.
