A Comparison of a Maximum Likelihood and a Bayesian Ability Estimation Procedure for Tailored Testing.
Rosso, Martin A.; Reckase, Mark D.
The overall purpose of this research was to compare a maximum likelihood based tailored testing procedure to a Bayesian tailored testing procedure. The results indicated that both tailored testing procedures produced equally reliable ability estimates. Also an analysis of test length indicated that reasonable ability estimates could be obtained using 12 to 14 items. It was also seen in the results that the maximum likelihood tailored testing procedure yielded significantly less total test information than did the Bayesian tailored testing procedure. The major difference between the two procedures seems to be in the significantly different ability estimates that they yielded. The maximum likelihood procedure is the procedure of choice if an adequate prior distribution is not available. (Author/BW)
