The Effect of Test Length and IRT Model on the Distribution and Stability of Three Appropriateness Indexes.
Noonan, Brian W.; And Others
Applied Psychological Measurement, v16 n4 p345-52 Dec 1992
Studied the extent to which three appropriateness indexes, Z(sub 3), ECIZ4, and W, are well standardized in a Monte Carlo study. The ECIZ4 most closely approximated a normal distribution, and its skewness and kurtosis were more stable and less affected by test length and item response theory model than the others. (SLD)
