When trying to explain SCAT scores - would it be fair to extrapolate from the test that a child who scored in the 90% percentile on the test (this is just an example) would have score in approximately the 99.5% if the test was given to the general population. I am figuring this by the fact that the test is allegedly given only to top 5% of children on other standardized tests - so:
If 1000 children take a regular standardized test, 50 of them would qualify to take SCAT. A child who scored in the 90th percentile on SCAT would thus be one of 5 of 1000 = 99.5th percentile?
My strength is def. not math or statistics, and I know there are all sorts of other variables - I am just trying to figure out a way to give some sense of where the score would land a kid among the general population.
Thanks, Cat
