The median is the middle number in a group of sorted numbers. The numbers can be sorted either way — ascending or descending. Sorting won’t change the median value. The median is a more descriptive representation of a set of numbers than the average. Especially with outliers, which create skew and can distort the mean, the median can be more useful. When there is an odd set of numbers, the median is the middle number. When an even set of numbers is used, we have two middle numbers. In this case, the two middle numbers are added together and divided by two to get the median.
