A measurement approach called generalizability theory (G-theory) is an important alternative to the more familiar classical measurement theory that yields less useful coefficients such as alpha or the KR-20 coefficient. G-theory is a theory about the dependability of behavioral measurements that allows the simultaneous estimation of multiple…

Kim, Yang Boon; Lee, Jong Sung – 1990
The empirical validity of generalizability theory was investigated by applying two three-facet designs to data obtained in 1988 from administration of the Scientific Thinking and Research Skill Test (STRST). The decision validity of the STRST was also examined. Subjects were 125 fifth-grade and 125 sixth-grade students who were administered the…
