The Reliability of a Linear Composite of Nonequivalent Subtests.
Rozeboom, William W.
Applied Psychological Measurement, v13 n3 p277-83 Sep 1989
Formulas are provided for estimating the reliability of a linear composite of non-equivalent subtests given the reliabilities of component subtests. The reliability of the composite is compared to that of its components. An empirical example uses data from 170 children aged 4 through 8 years performing 34 Piagetian tasks. (SLD)
