## Definition of 'Median'

The median is a statistical measure that can be used to describe the central tendency of a data set. It is the middle value in a data set when the values are arranged in order from smallest to largest. If there is an odd number of values in the data set, the median is the middle value. If there is an even number of values in the data set, the median is the average of the two middle values.

The median is often used in place of the mean when there are outliers in a data set. Outliers are values that are significantly different from the rest of the data. The mean can be skewed by outliers, but the median is not affected by them.

The median can also be used to compare two or more data sets. If the medians of the two data sets are the same, then the two data sets have the same central tendency. If the medians of the two data sets are different, then the two data sets have different central tendencies.

The median is a useful statistical measure that can be used to describe the central tendency of a data set. It is not affected by outliers and can be used to compare two or more data sets.
