Here's an interesting take on median:

It's worth noting that when you use linear discrepancy that there's no
difference between the various definitions of median of a list with an
even number of elements.
For example:
X=: 131 3 281 2 67 353
mean=: +/%#
dscL=: +/@(|@- ])
(dscL mean@((>.,<.)@-:@<:@# { /:~)) X
693
(dscL <.@-:@<:@# { /:~) X
693
(dscL >.@-:@<:@# { /:~) X
693
