An Examination of the Bilevel Dimensionality of Lower and Higher Mental Processes in Probability Achievement
Weber, Margaret B.
Educational and Psychological Measurement, 37, 4, 987-90, W 77
Bilevel dimensionality of probability was examined via factor analysis, Rasch latent trait analysis, and classical item analysis. Results suggest that when nonstandardized measures are the criteria for achievement, relying solely on estimates of content validity may lead to erroneous interpretation of test score data. (JKS)
