Calculation of Cronbach's Alpha Coefficient, Generalizability Index (GI), and Dependability Index (DI) in the Model Types of Survey Design
서베이 설계 모형별 Cronbach's Alpha 계수와 GI, DI 산출방안
Abstract
The paper reviews Cronbaha's coefficient to measure a single source of error. On the contrary to classical measurement theory, the generalizability study can be used in the social survey design to calculate Generalizability Index (GI) and Dependability Index (DI) for measuring multiple sources of errors of behavior evaluation. The study proposes application guidelines to implement R:(
