Did you try what I suggested?
If you go to www.rseek.org and search for "odd or even integers" you
will get various solutions.
You could even write your own test by comparing x/2 with round(x/2).
Also, it's good form to copy the list on your replies, not just me.

How would I go about saying the median = element x in terms of n (say (n + 1)/2 or whatever it would be) if there is an even amount of elements, or x in terms of n (with a different way of saying how many n) if there is an odd amount of elements?
