This program for PCs accompanies the paper: Crawford, J. R., & Garthwaite, P. H. (2008). On the "optimal" size for normative samples in neuropsychology: Capturing the uncertainty when normative data are used to quantify the standing of a neuropsychological test score.Child Neuropsychology, 14, 99-117.
The program (QUAND.exe) quantifies the uncertainty arising from the use of normative sample data to estimate the standing of a raw score (there are two options: the first allows neuropsychologists to quantify the uncertainty attached to existing normative data; the second is aimed at neuropsychologists planning a normative study).
