Odd and even data sets
For an odd count, the single central value is used. For an even count, the two central values are averaged and shown explicitly.

Quartiles use the median-of-halves method: when the data count is odd, the overall median is excluded from both halves.
How it works
See the middle instead of trusting a black box.
Sorting and highlighting make the result immediately checkable, while the quartile summary adds useful context about spread.
- 01
Enter the data
Paste values separated by commas, spaces, semicolons, tabs, or new lines.
- 02
Follow the sorting
The calculator orders every valid value from smallest to largest and highlights the middle position or positions.
- 03
Read the distribution
Review the median alongside Q1, Q3, interquartile range, full range, and a clear odd-or-even explanation.
A clear statistical summary
Median, middle positions, and distribution together.
Visible sorted values
Every number appears in numerical order with the median-defining position highlighted, making the result easy to verify.
Quartile context
Q1, Q3, IQR, minimum, maximum, and full range give a compact view of the data's center and spread.
Median questions
Sorting, even data, quartiles, IQR, and privacy.
How do you find the median?+
Sort the values from smallest to largest. If the count is odd, use the middle value. If it is even, average the two middle values.
Is median the same as average?+
No. The median is the middle of ordered data, while the arithmetic average is the sum divided by the count. The median is often less affected by extreme values.
How are quartiles calculated?+
This calculator uses the median-of-halves method. When the value count is odd, the overall median is excluded before finding Q1 and Q3.
Can I use duplicate or negative numbers?+
Yes. Duplicates, negative numbers, decimals, and scientific notation are all accepted and sorted numerically.
What is the interquartile range?+
The IQR is Q3 minus Q1. It describes the spread of the middle half of the data.
Are my values saved or uploaded?+
No. The calculation runs locally in your browser and the entered values are not stored.
