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.
- 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.
- Count the number of items there are in the set
In this example, there are 11 items in the set
- 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}.
