A norm distribution consisting of test scores received by 810 college students on a 150 item dichotomously-scored four-alternative multiple-choice test was empirically estimated through several item-examinee sampling procedures. The post mortem item-sampling investigation was specifically designed to manipulate systematically the variables of…

Shoemaker, David M. – 1970
Selected parameters for a negatively-skewed and a normally distributed normative distribution were estimated in a post-mortem item-examinee sampling investigation. Manipulated systematically were number of subtests, number of items per subtest, and number of examinees responding to each subtest. Each item-examinee sampling procedure was replicated…

Shoemaker, David M. – 1972
Investigated empirically through post mortem item-examinee sampling were the relative merits of two alternative procedures for allocating items to subtests in multiple matrix sampling and the feasibility of using the jackknife in approximating standard errors of estimate. The results indicate clearly that a partially balanced incomplete block…
