How do you find the median if the amount of data is even?

If the number of data is even, the median can be found by listing all the data from least to greatest (or from greatest to least, it doesn't matter), crossing out one per side until you are left with two data, and then averaging the two data. For example:

1 2 3 4 5 6

First you cross out 1 and 6, then 2 and 5, so you are left with the middle two, 2 and 3. You average them by adding them together and then dividing by 2.

3 + 2 = 5

5/2 = 2.5

The median is 2.5.
