Expanding reliability generalization: confidence intervals and Charter's combined reliability coefficient.
Methods of reliability generalization characterize the reliability of a scale's scores across studies. Charter in 2003 presented useful formulae for computing combined estimates of reliability. The present article illustrates use of Charter's formulae and application of confidence intervals for reliability coefficients, including the combined estimate. Researchers may find these methods for reliability generalization useful.
