Demonstration of The Multiple Matrices Sampling Technique In Establishing The Psychometric Characteristics Of Large Samples

Abstract

The multiple matrixes sampling technique is an approach to achieving broad curriculum coverage while minimizing testing time per student. This involved developing a complete set of items judged to cover the curriculum, then dividing them into subsets and administering the subsets to samples of pupils. This method, by limiting the number of items administered to each pupil, limits the amount of testing time required, while still providing, across students, coverage of a broad range of content. In a recent study, a test battery with 127 items in three sets was developed and standardized with the aid of the multiple matrices sampling method. By adopting this method, the study has demonstrated the possibility of validating a large number of items without unnecessarily disrupting the academic program of the pupils.
