BRIEF REPORT - BARTLETTS TEST OF SPHERICITY AND CHANCE FINDINGS IN FACTOR ANALYSIS

Bartlett's test of sphericitg: Was applied to a correlation matrix computed on random normal deviates by Armstrong and Soelberg (1968), and returned a chi square value indicating that the matrix could have been generated from a population where the correlation coefficients are zero. These results re- emphasize the desirability of computing this test prior to proceeding t o factor extraction, and in accord with the findings of other writers, indicate this test to be sensitive in detecting results which can be ascribed to chance. © 1969, Taylor & Francis Group, LLC.
