TY - JOUR T1 - Features of the sampling distribution of the ability estimate in computerized adaptive testing according to two stopping rules JF - Journal of Applied Measurement Y1 - 2010 A1 - Blais, J. G. A1 - Raiche, G. AB - Whether paper and pencil or computerized adaptive, tests are usually described by a set of rules managing how they are administered: which item will be first, which should follow any given item, when to administer the last one. This article focus on the latter and looks at the effect of two stopping rules on the estimated sampling distribution of the ability estimate in a CAT: the number of items administered and the a priori determined size of the standard error of the ability estimate.

KW - *Bias (Epidemiology) KW - *Computers KW - Data Interpretation, Statistical KW - Models, Statistical AB - In a computerized adaptive test, we would like to obtain an acceptable precision of the proficiency level estimate using an optimal number of items. Unfortunately, decreasing the number of items is accompanied by a certain degree of bias when the true proficiency level differs significantly from the a priori estimate. The authors suggest that it is possible to reduced the bias, and even the standard error of the estimate, by applying to each provisional estimation one or a combination of the following strategies: adaptive correction for bias proposed by Bock and Mislevy (1982), adaptive a priori estimate, and adaptive integration interval.
