Mean, median & mode calculatorThe three averages of a data set at once — the mean (arithmetic average), the median (middle value) and the mode (most frequent) — plus the range. When several values tie for most frequent, they are all shown.Median absolute deviation calculatorA robust measure of spread: the median of the absolute distances from the median. It shrugs off outliers where the standard deviation would blow up.

The Median calculator turns Numbers into Median, Min, Max, instantly and for free. For instance, with Numbers = 12, 18, 20, 25, 30 it returns Median = 20, Min = 12 and Max = 30.

How to use it

  1. Enter your values: Numbers.
  2. Read the result instantly: Median, Min, Max.

Frequently asked questions

What does the Median calculator actually compute?

It takes Numbers and derives Median, Min and Max from them. The calculation is live as you type, so the result updates on every change.

What information do I need to provide?

A single value: Numbers. Nothing else is required — no account, no file upload.

Can you show a worked example?

With Numbers = 12, 18, 20, 25, 30, the calculator returns Median = 20, Min = 12 and Max = 30. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

What happens if I enter larger values?

It moves a lot. Using Numbers = 12, 19, 22, 29, 36 instead, Median goes from 20 to 22 — which is why it is worth testing a few scenarios rather than trusting a single figure.

What does it give for smaller values?

Scaled down to Numbers = 12, 18, 20, Median comes out at 18. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Summarising a dataset before drawing conclusions from it, checking whether a difference between two groups is real, and putting an interval around an estimate.

What is the most common mistake?

Reading a p-value as the probability that the hypothesis is wrong. It is the probability of seeing data at least this extreme if the null were true — a different statement, and a much weaker one.

What is the difference between the Median calculator and the Mean, median & mode calculator?

This one returns Min and Max; the Mean, median & mode calculator returns Mean and Mode. That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

Median absolute deviation calculator is the closest one after this: A robust measure of spread: the median of the absolute distances from the median. It shrugs off outliers where the standard deviation would blow up. Multiply by 1.4826 to estimate the standard deviation of clean data.

What else is worth having open alongside it?

Statistics calculator and Average (mean) calculator — they come up in the same task often enough to be worth a second tab.
