# Median of a Set of Numbers

**Formula:** `M = median(...numbers)`

## Introduction to Median Calculator

The median of a set of numbers is the middle value when the numbers are arranged in ascending order. If there is an even number of observations, the median is the average of the two middle numbers.

## Parameter usage:

`...numbers`

= a set of numbers.

## Example valid values:

`1, 3, 3`

= 3`1, 2, 3, 4`

= 2.5

## Output:

`median`

= the median value of the set of numbers

## Data validation

Numbers must be real numbers. There's no intrinsic range validation necessary for median calculation as it does not depend on the magnitude of numbers but rather their relative distribution.

## Summary

This calculator determines the median value of a set of numbers. It is useful in statistics, research, data analysis, and more.
