Median
The middle value of a dataset when the numbers are sorted in order.
The median is the value that sits exactly in the middle of a dataset once it is sorted from smallest to largest. If there is an even number of values, the median is the average of the two middle ones. Unlike the mean, the median is resistant to outliers, which is why incomes and house prices are usually reported as medians — one billionaire doesn't drag it the way it would the average.
Example: The median of 2, 4, 9, 50 is (4 + 9) ÷ 2 = 6.5, while the mean is 16.25.
