A composite score is the sum of a set of components. For example, a total test score can be defined as the sum of the individual items. The reliability of composite scores is of interest in a wide variety of contexts due to their widespread use and applicability to many disciplines. The psychometric literature has devoted considerable time to discussing how to best estimate the population reliability value. However, all point estimates of a reliability coefficient fail to convey the uncertainty… CONTINUE READING
