Abstract : Measures of consistency and completeness of order relations derived from testtype data are proposed. The measures are generalized to apply to incomplete data such as tailored testing. The measures are based on consideration of the itempluspersons by itemspluspersons matrix as an adjacency matrix in which a 1 means that the row element dominated the column element regardless of whether it is item or person which dominates. From this the number of itemitem and personperson dominance relations can be derived. Indices of consistency are developed which compare the number of dominance relations in a matrix to the number that would occur if it were perfectly consistent and to the number in a random matrix. The indices of consistency are shown to relate to test variance, the KuderRichardson formulas, and Loevinger's homogeneity indices. Indices of completeness are also proposed. (Author)
