I think it would be reasonable, and perhaps preferable, to use just
"median" for the semantics described in most dictionaries -- for
example, this:
http://www.merriam-webster.com/dictionary/median
If you do a google search for "median" and poke around, you'll find
many places where this is the only definition mentioned; the others
seem to be rather infrequently used.  Why not make the commone usage
convenient?
