Nice try in making in seem like there are TONS of research out there.

These four links refer to the same study.

This article compares 26 home-schooled students to 13,000 state students and 1 million nationwide students. Anyone who knows something about statistical analysis knows that comparing such a small sample to very large samples render the study meaningless.

This link has NO study listed

This article states: "median score of home schooled children was low in mathematical computation (42nd percentile)". Oops!

An essay by a ninth grader is not legitimate research.
Even the studies that you did post (I'm sorry, the ONE legitimate study you posted) fail to prove your assertion that "research demonstrates that homeschooled 'Christian' children out test the stuffing out of national averages."
Why don't you go find "From the Extreme to the Mainstream" by Patrick Basham. It is a publication of the Fraser Insitute in Vancouver BC that gives a summary of the research up through, perhaps, 2001. Basham is now with a DC think tank.
Try nheri.org. The National Home Education Research Institute has pages of high quality research. IIRC, the organization was started by a University of Maryland professor who set out to prove that homeschooling was bad, and ended up proving the opposite.
When polling nationalpolitical opinion, pollsters typically poll from 300 to 1500 individuals, and that is considered quite valid, so how is the ratio of 26:13000 so out of line? The real question is how well the 26 represent the body of home schoolers.
