About Average Calculator
Mean, median and mode answer different questions, and picking the wrong one is how statistics mislead. The mean is pulled hard by outliers — one billionaire in a room of a hundred people raises the average wealth enormously while the median barely moves. Report the median for skewed data like income, house prices or response times.

Questions
Why is there no mode shown sometimes?
Because every value appears exactly once, so there is no most-common value. A mode only exists when at least one number repeats.
Which standard deviation is this?
The population figure, dividing by n. If your numbers are a sample drawn from something larger, use the Standard Deviation Calculator, which also gives the n−1 sample version.
Is the arithmetic exact?
It uses double-precision floating point — about 15 significant figures, far more than the inputs justify. Displayed rounding is cosmetic; the underlying numbers are not rounded between steps, so chained results do not drift.
