Resampling permutation probability values for Cronbach's alpha.
A permutation procedure to compute a resampling probability value and empirical quantile limits is provided for Cronbach's alpha measure of internal reliability. The underlying assumptions for the conventional use of alpha are discussed. The use of a permutation test for Cronbach's alpha is highlighted as a valuable tool when sample sizes are small and necessary assumptions cannot be met.
