Frequently asked questions
What's the difference between mean and median?
The mean adds and divides; the median is the middle value. An extreme value shifts the mean a lot but the median very little.
How do I enter decimals?
Use your language's decimal separator. Avoid thousands separators so each number is read correctly.
