Assessing the Dimensionality of NAEP Reading Data.
Zwick, Rebecca
Journal of Educational Measurement, v24 n4 p293-308 Win 1987
National Assessment of Educational Progress reading data were scaled using a unidimensional item response theory model. Bock's full-information factor analysis and Rosenbaum's test of unidimensionality were applied. Conclusions about unidimensionality for balanced incomplete block spiralled data were the same as for complete data. (Author/GDC)
