Definitions
Mean (average): Sum of all values divided by count. Sensitive to outliers.
Median: The middle value when sorted. Robust to outliers — preferred for skewed data like salaries or house prices.
Mode: The most frequently occurring value. A dataset can have multiple modes, or none if all values are unique.
Range: Max minus Min. Simple measure of spread.
Mean vs median — which to use?
For symmetric distributions, mean and median are similar. For skewed data (like income), the median is a better "typical" value because the mean is pulled toward extreme values. That's why median household income is reported instead of mean.
