The equivalence of three statistical packages for performing hierarchical cluster analysis

Three different software programs which contain hierarchical agglomerative cluster analysis procedures were shown to generate different solutions on the same data set using apparently the same options. The basis for the differences in the solutions was the formulae used to calculate Euclidean distance. Users of statistical software were warned of terminological confusion concerning cluster analysis.This research was supported by a National Science Foundation grant (DCR#74-20007) entitled A Consumer Report on Cluster Analysis Software. I wish to thank the authors of the three programs for their helpful comments on the paper.     

The relationship of sexual attitudes,attitudes about women,and racial attitudes in white males

A questionnaire measuring sexual attitudes, attitudes about women, and racial attitudes was administered to 350 White male college students. Sexual attitudes characterized by sexual guilt, emphasis on personal and social control of sexual expression, and depersonalization of sex were significantly positively correlated (p<.001) with attitudes that typified women in terms of traditional masculine—feminine stereotypes and good (nonsexual)—bad (sexual) dichotomies. These stereotyped and dichotomous attitudes about women and constricted and depersonalized sexual attitudes were both significantly positively correlated (p<.001) with negative racial attitudes. The implications of these results and other research suggested by this investigation are discussed.This report is based on a dissertation submitted in partial fulfillment of the requirements for the Ph.D. degree at Michigan State University, 1973. The author would like to express appreciation to Dozier W. Thornton for continued guidance and assistance as dissertation advisor. In addition, the author gratefully acknowledges the assistance of Donald L. Grummon, Andrew M. Barclay, and Jeanne E. Gullahorn, all of whom served on the dissertation committee.
