Finds the middle value of a dataset once it’s sorted from smallest to largest.
How it works
The dataset is sorted, then the single middle value is returned — or, for an even count, the average of the two middle values.
What this does not include
This does not include mean or mode alongside the median — this calculator specifically returns the median value only, matching that narrower search intent directly.
How to use this calculator
- Enter your dataset as comma-separated numbers.
A worked example
Dataset 3, 1, 4, 1, 5, 9, 2 (7 values, odd count) sorts to 1, 1, 2, 3, 4, 5, 9 — the middle value is 3.
Dataset 3, 1, 4, 1, 5, 9 (6 values, even count) sorts to 1, 1, 3, 4, 5, 9 — the two middle values (3 and 4) average to 3.5.
What the calculation does
| Dataset size | Median is |
|---|---|
| Odd count | The single middle value after sorting |
| Even count | The average of the two middle values after sorting |
Edge cases worth knowing
A single-value dataset has that value as its own median — there’s nothing to sort or average.
Median ignores how extreme the outer values are, only their position — a dataset of 1, 2, 3 and one of 1, 2, 300 share the identical median (2), even though their spread is wildly different.
Frequently asked questions
Why use median instead of mean (average)?
Median resists distortion from extreme outliers, since it only cares about the middle position rather than every value’s magnitude — a useful property for skewed data like incomes.
What happens with an even number of values?
There’s no single middle value, so the two middle values are averaged together to give the median.
Does the order I enter values in matter?
No — the calculator sorts the data automatically before finding the median, regardless of the order you type it in.
