Ketidaktepatan Penggunaan Validitas Butir dan Koefisien Reliabilitas dalam Penelitian Pendidikan dan Psikologi

Abstract

Item validity is applied in educational and psychological research through item analysis to enhance the reliability of respondent scores. Recently, there are a couple of inappropriate ways of treating item validity, which neither ensures the reliability nor justifies the validity of the measurement. Similar cases also happen in the application of reliability coefficient.
