[quote=Anonymous][quote=Anonymous]Learn Statistics. 9% is of all people taking the test score above 91%. Fairfax county children seem to be smarter than average....but they are taking the test at younger age. The number taking Algebra in the 7th grade is probably around 15-18%: 2000-2500 kids out of 13000. Not all of these kids are in AAP, though. [/quote] Umm, percentile rank is not the same as percentage. If a student scores above 91%, it doesn't necessarily mean they are in the 91 percentile rank :roll: Just to simplify things, if 100 total students took the test and the first nine students had scores like "100%, 99.7%, 98.4%, 98.2%, 97.6%, 97.3%, 96.5%, 96.1% and 95.9%" only those students will be at or above 91 percentile. A student who scores 95% will not make it in the 91 percentile or above rank, even though thee score is great. Got it? Most people confuse percentile with percentage.[/quote]
