[quote=Anonymous][quote=Anonymous][quote=Anonymous]That's why they look at percentile and not the raw score. It's not statistically significant given the margin of error at the tail.[/quote] But 99-99-99 is different from 98-99-99.[/quote] But the 99-99-99 or 98-99-99 are percentiles and NOT raw scores or scale scores. The MAP scores are something different altogether, they are RIT scores, a score calculated by NWEA based on several factors. Standardized testing scores rely on a LOT of psychometrics, they are not strictly # correct or # incorrect. [/quote]
