Webreliability for different method of splitting of the test. Rudner et.al. (2002) observed that split-half reliability is a function of how the test was split. A solution to the problem is provided by Cronbach‟s alpha which is interpreted by many researchers as the average of all possible split-half correlations (Cortina, 1993). WebMaximization of Item Covariances. Callender and Osburn described a method that optimizes the split-half coefficient by assigning items to the two test halves so that the sum of the item covariances is maximized. The procedure, referred to as MSPLIT, results in reliability estimates higher than KR20 and odd–even splits.
