How to use it

Paste up to 10,000 numbers separated by commas or spaces.

Good to know

All values use JavaScript floating-point arithmetic.

Summarize a short number list

Separate values with commas, spaces, or line breaks. For 12, 18, 24, 30, the average is 21; the median is also 21, the sum is 84, and the count is 4.

Read the statistics together

The mean is the sum divided by the count. The median is the middle value after sorting, which can be more representative when one value is unusually large or small. The minimum and maximum reveal the range at a glance.

Use up to 10,000 finite numbers. Calculations use JavaScript floating-point arithmetic, so values with many decimal places can need rounding for presentation. This does not validate a dataset or decide which statistical measure fits a question.
