[quote=Anonymous][quote=Anonymous][quote=Anonymous]The whole reason fcps went to fat instead of cogat was to get a real percentile of fcps students in second grade, to get data relevant to fcps.  You can't normalize a test on the national level when the universe consists only of fairfax kids.  At best you could normalize the test for the FAT, but no guarantee there would be any statistical significance in the need to age adjust.  In reality there is no coherence in the cogat and fat.  If fcps wanted overinflated data, they would have just kept the old cogat scoring system.[/quote]

Says the voice of reason in a very unreasonable thread.[/quote]

So the two posters above, who are speaking "the voice of reason" are statisticians?   13,000  is a sample that is too small to age normalize?  Maybe yes, maybe no, but I am not sure.  Are you?   If you do not know what you are talking about, please do not post statements without any scientific support but only conjecture.  And if you don' t know what the OP is saying, do not agree and call it reasonable when you have no knowledge in the area.  [/quote]
