Three techniques for assessing the adequacy of correlation matrices for factor analysis were applied to four examples from the literature. The methods compared were: (1) inspection of the off diagonal elements of the anti-image covariance matrix S(to the 2nd) R(to the -1) and S(to the 2nd); (2) the Measure of Sampling Adequacy (M.S.A.), and (3) Bartletts Test of Sphericity. Of the four matrices used for the study, two were comprised of eight variables and one each of fourteen and twenty. The sample sizes ranged from 50 to over 3,000. The results indicated that the three methods for overall assessment yeidlded comparable results. It was recommended, however, that methods for individual variables assessment also be used. (Author)
