The MacQuarrie Test for Mechanical Ability: II. Factor analysis

Abstract

The 7 subtest scores of 329 radio assembly operators were correlated to provide a matrix for factor analysis by the Thurstone Centroid Method. Two factors stood out as being clearly defined: the first was a space factor, the second a controlled movement factor, while a third, tentatively designated a visual inspection factor, appeared in 3 of the tests and not in the others and gave no loadings considered to be significant.
