Median

Median is a little bit different. The way you compute the median of the dataset is by sorting all the values (in either ascending or descending order), and taking the one that ends up in the middle.

So, for example, let's use the same dataset of children in my neighborhood

0, 2, 3, 2, 1, 0, 0, 2, 0

I would sort it numerically, and I can take the number that's slap dab in the middle of the data, which turns out to be 1.

0, 0, 0, 0, 1, 2, 2, 2, 3

Again, all I do is take the data, sort it numerically, and take the center point.
