Hmm. So you trust the results of non-standardized non-normed tests, even though no such tests have actually been cited.
You are unwilling to trust the results of an internationally normed and standardized test (PISA) after controlling for some but not all exogenous variables?
But nevertheless, you are willing to trust the results of the internationally normed and standardized test without controlling for any exogenous variables?
Heh, you had me going for a while. Now I realize you are trolling.
