摘要

Thirteen samples were randomly drawn from the normative database for the latest edition of Knox's Cube Test- Revised (KCT-R). Parameter estimates for the Rasch model and two and three parameter logistic models were derived and compared. Sample size influenced these estimates as might be expected, Rasch parameter estimates consistently showed the smallest values by sample size using a goodness of fit index.
