"doesn't work AT ALL"?????

Ha! Gotcha!

It works when N=2!

|| Well, no, it doesn't work at all. The definition of Median
|| is a value where half your list of values is above, and half
|| is below. If the values all tend toward the mininum or the
|| maximum, this "equation" would be way out of line.

|| || || Would depend on just what you are looking for. A quick look at
|| || || Oracle's SQL functions showed avg, st. deviation, and variance
|| || || although no median but that should be easier to write than
|| || || some of the
|| || || others.
