Finding the median in a distribution of integers is relatively easy. When there is an odd number of scores: it is the one left over when counting in from either end. When there are an even number of scores, the median is whatever the middle two scores are (if they are the same) or the halfway point between the middle-most two scores when they differ from each other.

Medians are most often used when distributions are **skewed**. Indeed, when data is presented in medians, ask about the means. If they are quite different, the distribution is highly skewed, and the sample may not be as representative as you would like.

To calculate the median, arrange the scores in order of magnitude from high to low or from low to high (it doesn’t matter which one you choose). Select the score in the middle.

Take these number, and arrangement from high to low:

2

9

4

7

8

Here they are arranged in a distribution:

9

8

7

4

2

Find the score in the middle. In the following numbers, the median is 7:

8
