When a set of data has an even number of entries, there are two middle numbers. In this case, we find the median by taking the mean of the two middle numbers.

  1. Order the numbers form least to greatest.
  2. Add up the two middle numbers.
  3. Divide the total by 2 (since there are two middle numbers) to find the mean.

For example, look at this set:

23, 13, 30, 11, 9, 11

  1. Order the numbers from least to greatest: 9, 11, 11, 13, 23, 30
  2. Add up the two middle numbers: 11 + 13 = 24
  3. Find the mean of 24: 24/2 = 12

The median of this set is 12.
