About the Median Calculator

Find the middle value of a data set, which is not affected by extreme values.

How to use the Median Calculator

  1. Enter your numbers in Input Series, separated by commas or spaces.
  2. Press Calculate.

Formula and method

Sort the values. If there is an odd number of values, the median is the middle one. If even, it is the average of the two middle ones.

Worked example

12, 45, 7, 23, 9, 31 sorts to 7, 9, 12, 23, 31, 45. The median is (12 + 23) ÷ 2 = 17.5.

Tips

  • The median is better than the mean for skewed data such as incomes or house prices.
