Watch the animation for calculating the median value and then consider the question below.

**Why use this technique? Is it appropriate?**

The Median is a useful calculation when you have a number of anomalies (large or small numbers in a data set) which could skew the results if you were to use the mean as a calculation. For instance if you studied the wealth of a country's population, the median is likely to indicate a figure of the earnings, closer to the majority of the people, than calculating the mean would.
