Memo to Researchers on the Rationalized Arcsine Transform

ArcsineMemo to researchers who rely on the Rationalized Arcsine Transform: If you need to use RAU’s to pick flyshit out of pepper near the ceiling or floor, your study methodology is fucked. Read how scoring QuickSIN was designed, to spread out the results for meaningful analysis; or alternately use something like HINT scoring by varying the SNR so your subjects get 50% correct… And then go back to your drawing board to redesign your bungled study.
