This study investigated the effects of a fixed and variable entry procedure on bias and information of a Bayesian adaptive test. It was found that neither the fixed nor the variable entry procedure produced biased ability estimates on the average. Both procedures did produce, however, biased ability estimates at the extremes of the ability distribution. Both procedures produced peaked and asymmetric information curves, rather than ideal flat curves. Relative efficiency curves indicated that at no point along the ability continuum was one procedure more efficient than the other. The two procedures chose different item subsets for administration. In almost half the cases, the variable entry procedure required more items to reach termination. / Source: Dissertation Abstracts International, Volume: 47-08, Section: A, page: 3013. / Thesis (Ph.D.)--The Florida State University, 1986.
