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".
