Statistics Calculator (Mean, Median…)

About this calculator

This calculator takes a list of numbers you enter and returns the core descriptive statistics in one pass: the mean (average), median (middle value), mode (most frequent value), minimum and maximum, range, and standard deviation — the measure of how spread out the values are around the average.

It is used by students checking homework or exam-prep problems, researchers and analysts getting a quick summary of a small dataset without opening a spreadsheet, and anyone — from a teacher averaging test scores to a small business owner looking at sales figures — who needs a fast statistical snapshot of a handful of numbers.
