Median Calculator
The median is the middle value in a list of numbers arranged in ascending order. It is a key statistical measure that represents the central tendency of a data set. Unlike the average (mean), the median is less affected by extremely high or low values (outliers), making it a robust measure of central location.
For example, in the data set [3,5,7,9,11], the median is 7 — the middle number when arranged in order.
