Abstract:
A factorial analysis was made of data from the Normative Survey Battery of the March 1948 population of basic airmen. Tests which were submitted to the analyses include the Air Classification Battery, the Army General Classification Test, The AG Mechanical Aptitude Test, the Differential Aptitude Test Battery, and the Gray-Votaw General Achievement Test. The distributions of scores were normalized and intercorrelated. Eight centroid factors were extracted from the matrix of intercorrelations and rotated to psychologically meaningful positions. Two solutions were obtained, one based on orthogonal (independent) factors and the other based on oblique (dependent) factors. The tests in the battery are reviewed in terms of their factorial content, and recommendations are made for revisions of tests and changes in the composition of the battery.
