On Information of Percentile Ranks.
de Gruijter, Dato N. M.
Journal of Educational Measurement, v34 n2 p177-78 Sum 1997
K. May and W. A. Nicewander recently concluded (1994) that percentile ranks are inferior or raw scores as indicators of latent ability. It is argued that their conclusions are incorrect, and an error in their derivation is identified. The incorrect equation results in an incorrect conclusion, as work by F. M. Lord (1980) also indicates. (Author/SLD)
