Klasična teorija vprašalnikov : delo diplomskega seminarja

Giacomelli, Timotej (author), Smrekar, Jaka (mentor)

Klasična teorija vprašalnikov (CTT) je ena izmed najbolj razširjenih oblik analize testiranja zanesljivosti lestvic vprašalnikov, ki jo tvorimo na vprašalniku kot celoti. Razložili bomo glavne predpostavke CTT analize in pogledali tri glavne modele za izpeljavo koeficienta zanesljivosti. Na najbolj splošnem primeru koeficienta zanesljivosti bomo uporabili faktorsko analizo, s pomočjo katere izračunamo potrebne koeficiente. Nato bomo na setu podatkov vprašalnika HADS uporabili razložene koncepte in prijeme ter izračunali koeficient zanesljivosti tega vprašalnika.

Abstract

Classical test theory (CTT) is one of the most widespread forms of analysis of reliability testing of test scales, which are performed on the test as a whole. In this thesis we will look at the main assumptions of the CTT analysis and the three main models for deriving the reliability coefficient. In the most general case of reliability coefficient, we will use Factor analysis to calculate the necessary coefficients. We will then use the explained concepts and approaches on the data set of the HADS test and calculate its reliability coefficient.

• Keywords: Classical test theory, Factor analysis, reliability coefficient, true score.
