The median is the middle number. In statistics, the median represents the middle value in a set of numbers when they are arranged in order from smallest to largest. If there is an odd number of values, the median is simply the middle number.
The median provides a measure of the central tendency and helps account for outliers or extreme values in data. For example, in the set (2, 4, 6, 8, 10), the median would be 6. If there is an even number of values, the median is the average of the two middle numbers. For instance, in the set (2, 4, 6, 8), the median would be (4+6) / 2 = 5.
