About the Average Calculator
The mean is the total divided by the count. It uses every value, which makes it precise and also makes it sensitive: one extreme number moves it a long way.
The median is the middle value when sorted, and ignores how extreme the outliers are. For incomes, house prices or response times it is almost always the more representative figure.
The mode is the most frequent value. It is the only average that works for categories rather than numbers, and a list where every value appears once has no mode at all.
