The purpose of the original post was not to argue over WHY home-schooled
kids do markedly better on standardized academic tests, but rather to
refute
with this statistical fact the ignorant attempt at slandering
home-schooling
as some sort of fringe cult whose students are profoundly inferior
performers. The statistics DO clearly show - for whatever reason - that
this
ignorant prejudice is clearly false.

Well, answering false information with more false (or selectively cooked)
information is not my idea of a successful argument, Pierre. Anyone trained
in stats and research methodology can see it, and it paints an ugly picture.

As any of the legitimate studies point out (including the one I pointed to),
the studies are weighted down with sampling bias from the very beginning.
There is no way to compare the performance of homeschooled kids versus
non-homeschooled.
