WebDescription. Cronbach’s alpha is an estimator of test reliability that is suitable for use in single applications of a test, typically in cross-sectional designs. Given a test composed of p items, Cronbach’s alpha assumes that all items are equivalent test units and corresponds to the reliability of the full test computed by extending the ... WebThey found that the KR 20 for a set of 237 test questions, made of subtestsseven, gave a reliability coefficient higher than those calculated for each subtest. Yet according to the nature of internal consistency measurement, using the composite to calculate KR 20 should give a lower coefficient than those obtained using subtests. carey connect booking
