Thx, but are you sure? Median is defined as the middle element in odd
distributions but is the average of the 2 middle elements in even distributions.
For quartiles (or generalized quantiles) its even worse: there are multiple
definitions for quartiles. I even had an article listed 11 definitions of
calculating the quartile:

been better if Boost had done the thinking for me :)
