Özet
Purpose: The present study aims to evaluate how the reliabilities computed using alpha, Stratified alpha, Angoff-Feldt, and Feldt-Raju estimators may differ when sample size (500, 1000, and 2000) and item type ratio of dichotomous to polytomous items (2:1; 1:1, 1:2) included in the scale are varied.
