There is no generally agreed upon method for determining quartiles - if you are not happy with
Excel's default, then choose your own method and implement it through a UDF in VBA.

I have both Excel XP and 2007 and neither does even numbered count Quartile
functions correctly. What gives? Why hasn't Microsoft fixed this?
