Abstract
Based on a stratified sample of fifteen-year old students in Singapore schools, exploratory factor analysis and confirmatory factor analysis were used to identify and cross-validate the factorial structure underlying two group intelligence tests, the AH4 Test of Intelligence and the Advanced Progressive Matrices and two group Piagetian tests, Science Reasoning Tasks and Arlin Test of Formal Reasoning. The structure of the first- and second-order factors underlying the tests was first identified using exploratory factor analysis on Sample 1 (N = 230), the exploratory sample. The confirmatory approach using LISREL was then used to cross-validate the first- and second-order factor structure of the exploratory model on Sample 2 (N = 229), the validation sample. One second- and four first-order factors were found. To allow for easier interpretation of the factors, a Schmid-Leiman transformation was carried out on the first- and second-order factor matrices of the pooled sample (N = 459). The Schmid-Leiman transformation replaced factors in the two orders with a hierarchical factor matrix consisting of a general factor and four group factors: a formal operations factor, a spatial factor, a numerical factor and a verbal factor.
