Özet

In this research, the classical test theory and generalizability theory analyses were carried out with the data obtained by a job performance scale for the years 2005 and 2006. The reliability coefficients obtained (estimated) from the classical test theory and generalizability theory analyses were compared. In classical test theory, test retest and Cronbach's alpha reliability coefficient, Kendall's concordance coefficient for interrater reliability; in generalizability theory, G and Phi coefficients with multivariate model were computed and the consistency of these coefficients were examined. As the result of the research, it is seen that for the same measurement condition, the reliability coefficients obtained from the classical test theory and from the multivariate model of generalizability theory generated harmonious results. © 2010 Eǧitim Danişmanliǧi ve Araştirmalari İletişim Hizmetleri Tic.
