Summary

Results obtained by the Kudar-Richardson formula (20) adapted for use with R-KW scoring are compared with three other reliability formulas. Based on parallel tests administered at the same sitting the KR (20) estimates are compared with alternate-form correlations and with odd-even correlations adjusted by the Spearman-Brown prophecy formula. Comparisons are also made between KR (20) estimates and alternate-form correlations obtained for tests administered after intervals of six to ten months. All the results justify the use of the Kuder-Richardson procedure with tests that show no more than moderate speededness. (Author)
