Factor analysis is a technique of reducing a large number of correlated variables to a few main factors. It has been resorted to to overcome the limi-tations of univariate methods of analysis like correlations, path-coefficient and regression analysis (Wright, 1960; Walton, 1972). Besides, Moreno and Cubero (1978) have used it for estimating diversity.
