Webdengan menggunakan Inter-item Consistency Reliability yang melihat Cronbach’s coefficient alpha sebagai koefisien dari reliabilitas. Cronbach’s alpha adalah koefisien reliabilitas yang menunjukkan bagaimana bagian-bagian dari suatu set berkorelasi secara positif satu sama lainnya (Sekaran, 2003: 307). WebInter-item correlations address issues relating to a scale's fidelity of measurement, how well the instrument is measuring some construct (e.g., its internal consistency, Cronbach, 1951). Finding the judicious blend of overlap and diversity is the key issue to consider when examining correlational overlap among items (Allen & Yen, 2002 ). keysmash typing

WebJan 1, 1991 · The term ‘internal consistency’ has been used extensively in classical psychometrics to refer to the reliability of a scale based on the degree of within-scale item intercorrelation, as measured by say the split-half method, or more adequately by Cronbach's (1951) (Psychometrika, 16, 297–334) alpha, as well as the KR 20 and KR 21 coefficients.
