Some Comparisons of Four Order-Analytic Methods and Factor Analysis for Assessing Dimensionality.
Wise, Steven L.
While factor analysis is the most commonly proposed procedure for determining dimensionality, a recently developed procedure called order analysis may also prove to be useful for isolating unidimensional item sets. The first study in this report compares three order analysis procedures: Krus and Bart's (1974) procedure and Reynolds' (1976) procedures using two of Cliff's (1977) consistency indices. The comparisons were based on seven simulated data sets with known factorial dimensionality, and two multidimensional sets of mathematics data. The second Reynolds procedure reproduced the factor structure for the simulated data sets, but none of the procedures could reproduce the factors for the mathematics data. The second study in this report presents preliminary results using a new order-analysis procedure which solves some of the difficulties with reproducing factorial dimensionality. (Author/BW)
