## Explanation

When a set of data is sorted from smallest to largest number, it is possible to find the data point that is in the "middle" of the set of numbers.This number is not the average, but the number which is centrally located in the sorted sequence. If the the sorted data has an odd number of data points, the median is the one which is exactly in the middle. For example, if the numbers are 3,5, and 2, then the sorted data is 2, 3, 5, and the median is the number 3.

If the data set contains an even number of points, there are two values in the middle, and those two values are averaged. For example, if the sorted data contains the numbers 2, 5, 6, 7, then the two middle points are 5 and 6, and the median is the average of these values, or 5.5.
