q2 · i? · design · r2

Age-based re-analysis of the combined Sioux City and Duluth distributions: the separated 12-year-old group scored "the median for the 12 year olds was 23" on all three forms, with near-identical quartiles.

"The 12-year-old group was separated and distributed. In all three tests, A, B and C, the median for the 12 year olds was 23 and the quartiles were either on the same point or only one step removed."
