Factor Analyses of Parts 1 and 2 of the IIQ. Technical Report No. 6.1-72.
Pohlmann, John T.
A factor analysis was performed on 2,535 and 2,447 cases of the Instructional Improvement Questionnaire (IIQ) parts I and II, respectively. A correlation matrix for each part was calculated. Squared multiple correlations (SMC) for each item, using the other items as predictors, was placed in the main diagonal of the correlation matrix. The resulting matrix of item intercorrelations and SMC's was then factor analyzed using principle axis analysis. Tables present the results of the principle axis analyses for the two parts for all factors with Eigenvalues greater than 1.0. Inspection of the principle axis factor loading indicates that both parts have a rather strong general factor. The high latent roots associated with the first factor in each solution attest to this fact. The initial factors were rotated using the Varimax criterion. The rotated factor structures for both parts are presented in tables. (RC)
