The median is a statistical measure that represents the middle value in a set of numbers when they are arranged in ascending or descending order. To determine the median, you first need to arrange the numbers from lowest to highest or highest to lowest.

If you have an odd number of data points, the median is simply the middle value. For example, if you have the following set of numbers: 3, 7, 9, 12, 15, the median would be 9 because it is the value exactly in the middle.

However, if you have an even number of data points, the median is the average of the two middle values. For example, if you have the following set of numbers: 2, 4, 6, 8, the median would be (4 + 6)/2 = 5 because it is the average of the two middle values.

The median is a useful measure of central tendency because it is not affected by extreme values or outliers in the data set. It gives you an indication of the typical or middle value of a dataset and helps to identify the center of a distribution.
