📈 Mean vs Median

Suppose these are five salaries:
$35k, $38k, $42k, $44k, $2.5M

Mean (average): $531,800
Median (middle value): $42,000

The average suggests everyone is wealthy.
The median tells a completely different story.

👉 Whenever your data contains extreme values (called outliers), the median often represents the data much better than the mean.

That's why you'll often see median house prices and median income reported in the news.
