About this calculator
The arithmetic mean — sum divided by count — is the most familiar "average". It's the right choice for normally distributed data and homogeneous quantities. For skewed data, the median (the middle value) is usually more representative; for ratios over time, the geometric mean can be appropriate. Use mean for "average test score, average rainfall, average temperature".
Frequently asked
When the data has outliers or is heavily skewed (income, house prices). The median is robust against extreme values.
