Raatz, Ulrich – 1985
The use of factor analysis in examining the dimensionality of language tests is questioned and found to be problematic because it has a number of weak points which make it possible to manipulate results. Some of these weaknesses occur in the examinee selection sample, test selection, and the methods of extraction and rotation chosen. The use of…
