    A discriminant analysis of perceptions of women in a tenured business role
    (Wichita State University, Department of Psychology, 1977) Rappaport, A.; Hackett, D. W.
    This study explores the effect of long term holding on stereotypes which are believed to block the advancement of women into male dominated work areas. A mail questionnaire survey produced seven-point semantic differential scale data from 60 male and 51 female respondents in Real Estate sales. Stepwise discriminant analysis was applied to perceptions of salesmen by male and female respondents and perceptions of saleswomen by male and female respondents. No significant differences in perceptions of salesmen by both groups were found. When compared with female respondents, male respondents perceived saleswomen as: a) more emotional, b) more apprehensive, c) having weaker sales technique, and d) more reserved.

    Factorial validity by tautology: Methodological comments on Stewart and Stewart
    (Wichita State University, Department of Psychology, 1977) Dorans, Neil J.
    A recent attempt to assess the factorial validity of the Eight State Questionnaire used an unusual methodological procedure that is tautological in nature. Retention and rotation of all principle components to a trivial simple structure, in which each component is marked by one and only one scale, is guaranteed for any nonsingular correlation matrix. The certain existence of the transformation to this trivial structure precludes the use of its existence as scientific evidence of factorial validity. A verbal, geometric argument and a formal mathematical proof support the contention that this unusual methodology is tautological, and hence should be avoided in future research.

    The practicality of an orthogonal confactor rotation for the approximate resolution of oblique factors
    (Wichita State University, Department of Psychology, 1977) Cattell, Raymond B. (Raymond Bernard), 1905-1998; Brennan, Jerry
    The confactor rotational solution for the orthogonal case was estimated for possible use as an approximation to the more general oblique case. Two plasmodes were designed: one with seven variables and three factors and the other using 16 variables and six factors. In both plasmodes good rotational solutions were found when relatively small and moderate correlations existed among the factors. The Confactor rotational solutions for the orthogonal case was found to be a good approximation for the oblique case when the two parallel sets of data have the same correlations.

    A multivariate analysis of male athlete personality characteristics: Sport type and success
    (Wichita State University, Department of Psychology, 1977) Schurr, K. T.; Ashley, M. A.; Joy, K. L.
    One thousand five hundred-ninety six college students completed the 16PF Questionnaire and were then categorized by (1) involvement in athletics, (2) type of sport, and (3) level of success. An unbalanced hierarchical multivariate analysis of variance using Cattell's eight second stratum factors was then performed. Results support the contention that moderator variables involving sport type are of primary importance in the development of theory involving sports-personality relationships.
