متن کاملComparison of proficiency in an anesthesiology course across distinct medical student cohorts: psychometric approaches to test equating.
BACKGROUND Examinations are necessary for assessment of student proficiency in medical education, but comparison of achievement across different cohorts in different tests is challenging. We applied psychometric test equating methods to compare student proficiency in two different examinations for a clinical anesthesiology course. METHODS Each examination contained 50 multiple choice items an...
متن کاملA Modified Frequency Estimation Equating Method for the Common- Item Non-Equivalent Groups Design
Frequency estimation (also called post-stratification) is an equating method employed under the common-item nonequivalent groups design. A modified frequency estimation method is proposed here, based on altering one of the traditional assumptions in frequency estimation in order to correct for equating bias. A simulation study was carried out to compare equating errors for the modified frequenc...
متن کاملEffectiveness of the hybrid Levine equipercentile and modified frequency estimation equating methods under the common-item nonequivalent groups design
The purpose of this study was to evaluate the effectiveness of the hybrid Levine equipercentile (Hybrid LE) and modified frequency estimation (MFE) equating methods in improving accuracy of equating as compared to the percentile rank frequency estimation (FE), kernel frequency estimation (Kernel FE) and percentile rank chained equipercentile (CE) equating methods under the common-item nonequiva...
متن کاملChained Vector Simplex
An algorithm for solving linear programming problems whose matrix of coefficients contains a large number of "zero" entries is studied. This algorithm is more useful when it is generated as a sub-program in a real-time program. The singly linked lists for storing only the non-zero entries of the coefficients matrix is used. The modified Revised Simplex Method is also used for solving such probl...
