ITEM SAMPLING IN TEST THEORY AND IN RESEARCH DESIGN.

Abstract

New and less new concepts and results in the itemsampling model for mental test theory are summarized. It is shown that certain research studies--typically those concerned with group means--could use item-sampling methods to improve their efficiency of experimental design. Various sampling error formulas are derived, making it possible to determine whether and to what extent various uses of item sampling will increase the information gained by the research worker.
