To find the mean, add up all of the numbers and divide the sum by the number of numbers (which in this case is 6).

So the mean is 5

To find the median, count off about 3 spaces (just take half of the size of the list, which is 6) from the beginning of the list until you hit the middle. Now count count off about 3 spaces from the end of the list until you hit the middle.
-7, -5, , , 12, 18
Since the middle is in between the numbers 5 and 7, add them up and divide that sum by 2.

So the median is 6
