to find the median, line the numbers up from smallest to largest
5.0, 6.0, 7.0, 7.5, 8.0, 9.0, 10.0
then, go from outside in, alternating from left and right, crossing out numbers until you have 1 number left.
Example:
6.0, 7.0, 7.5, 8.0, 9.0, 10.0
6.0, 7.0, 7.5, 8.0, 9.0
7.0, 7.5, 8.0, 9.0
7.0, 7.5, 8.0
7.5, 8.0
7.5 is the median
