Abstract
Non-orthogonal factor analysis is examined as a possible aid in assessing the extent of illusory halo in survey responses. Data from several studies involving students' evaluation of teaching (SETs) are re-analyzed with this method. Several advantages of this method, as compared with examining the underlying correlations directly, are described.
