[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]You don't seem to understand the use of "percentile." A 99th percentile score can't be "common" because it means the student is above the score of 99% of other students. So that can't be "common."[/quote] You don't seem to understand the concept of uneven distribution. [/quote] You still don't get it. You can't have a lot of kids in the 99th percentile, because, again, it means the students' score is above 99% of other kids. You can give everyone an A, you can give everyone a medal for participating, but you can't give everyone a 99th percentile score.[/quote] You still don't get it. The MAP percentiles are based on national norms. It is absolutely possible, and true, that more than 1% of kids around "here" are 99%ile nationally. It's just like how, in a memory care facility, far more than 1% of the residents are in the 99%ile nationally for cognitive care needs. [/quote]
