Mean Median Mode Calculator
Average, middle value and most frequent — the statistics trio in one view.
The Mean Median Mode Calculator computes the three central-tendency statistics for any set of numbers — the mean (average), median (middle value) and mode (most frequent) — plus range, sum and the sorted list.
Each measure tells a different story: the mean summarizes everything but can be skewed by outliers (one billionaire raises the average income), the median resists outliers (half the values lie below it), and the mode reveals the typical case (the most common income). Comparing them is how you spot skew in real data.
Paste grades, salaries, measurements or any dataset and see all three at once, with the mode handling ties and no-mode cases correctly. Everything runs locally in your browser.

How to use the Mean Median Mode Calculator
- Enter numbers separated by commas, spaces or newlines.
- Read the mean — the arithmetic average.
- Read the median — the middle of the sorted values.
- Check the mode(s) — the most frequent value(s).
- Scan the range and sorted list below.
Frequently asked questions
What is the difference between mean, median and mode?
Mean adds all values and divides by the count (outlier-sensitive). Median is the middle value when sorted (outlier-resistant). Mode is the most frequent value. All three describe 'the middle' from different angles.
When should I use the median instead of the mean?
When outliers would mislead — salaries, home prices, response times. The median says 'half of values are below this', which outliers cannot drag around.
Can there be more than one mode?
Yes — a dataset with two equally frequent values is bimodal, and the tool lists every tied mode. If every value appears once, there is no mode, which the calculator reports honestly.
