Calculation rules
The arithmetic mean is the sum divided by the count. The median is the middle value after sorting; for an even count it is the mean of the two middle values. For 10, 20, 30 and 40, both mean and median are 25.
Questions and answers
How should I enter numbers and repeated values?
All entries have equal weight. Repeated values count repeatedly. Negative numbers and scientific notation are accepted. Enter one number per line or use spaces or semicolons; a comma-separated CSV list is not supported because commas may represent decimals.
