How Do You Find the Median of a Set of Numbers?

To find the median of a set of numbers, line the numbers up in numerical order and find the number in the middle. The median of a set of data is simply the number in the numerical middle.

  1. Line the data up in numerical order

    Put the data in sequential order, for example: 2, 4, 6, 9, 9, 11, 23, 25, 28, 28, 29.

  2. Count the number of items there are in the set

    In this example, there are 11 items in the set

  3. Find the one in the middle

    The middle item would be the sixth one from either end. In this example, 11 is the median of the set of numbers {2, 4, 6, 9, 9, 11, 23, 25, 28, 28, 29}.
