Six Single-Administration Reliability Coefficients for Criterion-Referenced Tests: A Comparative Study.
Downing, Steven M.; Mehrens, William A.
Four criterion-referenced reliability coefficicents were compared to the Kuder-Richardson estimates and to each other. The Kuder-Richardson formulas 20 and 21, the Livingston, the Subkoviak and two Huynh coefficients were computed for a random sample of 33 criterion-referenced tests. The Subkoviak coefficient yielded the highest mean value; Huynh's Kappa yielded the lowest. The two Huynh coefficients were highly positively correlated with the Kuder-Richardson 20 and 21 coefficients, and with each other; the Livingston and the Subkoviak indexes were highly correlated with each other. A two-factor principle components analysis suggested that the Subkoviak coefficient measured a test characteristic that differed from the classical internal-consistency coefficients. (Author/CTM)
