Online Statistics Calculator

Calculate mean, median, mode, and standard deviation from a list of numbers.

Frequently Asked Questions

How do I enter the numbers?
Enter numbers separated by commas, spaces, or newlines. Decimals are allowed.
What is the formula for standard deviation?
Population standard deviation (divide by N). For sample SD we could use N-1; this tool uses N.
What if there is no mode?
If no value repeats, we show 'No mode' or the smallest value; some implementations show all values.
