Description

This data come from Thissen et al. (1993, p.71) that examined performance of under- graduates on four spelling items ‘infidelity’, ‘panoramic’, ‘succumb’ and ‘girder’. Each spelling item was scored either as correct or incorrect. The sample includes 285 male and 374 female undergraduate students from the University of Kansas.
