You've made this assertion at least three times now, but I confess
that I've only ever learned one way to compute a median; and quick
Google searches for "median", "kinds of median", and few other
variants failed to turn up anything obvious either. It seems to me
that if median is good enough for Oracle, Sybase, Excel, and the nun
who taught my fifth-grade elementary school class, it ought to be good
enough for us, too. (Don't mess with Sr. Catherine!)
