Number List Statistics
Show sum, mean, median, mode, and spread for a list of numbers, with the method used.
Paste or type up to 500 numbers, separated by spaces, commas, or new lines. Use a dot for decimals (up to four places).
Your result
Enter at least one number.
How to use it
- Enter the numbers with a space, a comma, or a new line.
- Read the mean and the other rows.
- A blank mode means no value is repeated.
Examples
- 1, 2, 2, and 31 2 2 3. The count is 4, the sum is 8.00, the mean is 2.00, the median is 2.00, the mode is 2.00, the range is 2.00, and the deviation is 0.71.
- One number5. Every value is 5.00 and the deviation is 0.00.
- An empty listNo numbers. No result is shown.
Tool details and privacy
The mean is the sum divided by the count. For an even count the median is the average of the two middle numbers. If every number appears once, the mode is blank.
The deviation divides by the count of numbers, not by the count minus one. A tie for the mode shows every tied value.
Options
- The limit is 500 numbers. Numbers use two decimal places. The deviation is the population figure, not the sample figure.
Limits
- Amounts use two decimal places and up to 12 digits before the decimal point. Rounding is half up.
- 1,250 is rejected. Write 1250 or 1250.50.
- The limit is 500 numbers. This is not a sample statistical test.
Privacy
The numbers are calculated in your browser and are not sent to any server.

Why is the deviation not divided by n−1?
Because it is the population deviation, and the list is the whole population here.
What if no number repeats?
The mode stays blank.
Is the list saved?
