Simulation Studies of Two-Stage Ability Testing.
Abstract
Monte Carlo simulation procedures were used to study the psychometric characteristics of two two-stage adaptive tests and a conventional 'peaked' ability test. Results showed that scores yielded by both two-stage tests better reflected the normal distribution of underlying ability. Ability estimates yielded by one of the two stage tests were more reliable and had a slightly higher relationship to underlying ability than did the conventional test scores. Several improvements in the construction of two-stage tests are suggested for use in further research.
