As for the median value, there's a relatively easy way to do this in PHP:

1. Sort the array   (sort())
2. Count the number of elements in the array   (count())
3. Take the element that is equal to half the number of the elements
(rounded to an int, which way you round doesn't matter)

Might be off-by-1 but that's fixed easily enough.
