About the Mean, Median & Mode Calculator
A free calculator that computes every descriptive statistic from a pasted data set, with step-by-step working and a histogram.
What it is
Paste any list of numbers and instantly get the mean, median, mode, range, sum, count, min, max, and both population and sample variance/standard deviation — with the derivation shown step by step and a histogram of the distribution.
Key features
Flexible input parsing
Accepts numbers separated by commas, spaces, or new lines — paste straight from a spreadsheet.
Full descriptive statistics
Mean, median, mode, range, sum, count, min, max, and both variance/SD measures in one view.
Step-by-step derivation
Shows the exact substitution used to find the mean and median, including the sorted list.
Multimodal handling
Lists every tied mode, or clearly states "no mode" when all values are unique.
Histogram
An auto-binned bar chart visualizes the shape of your data's distribution.
Population vs sample
Both variance and standard deviation are computed and labeled distinctly.
