The relationship between true ability (operationally defined as the number of items for which the examinee actually knew the correct answer) and the effects of guessing upon observed test variance was investigated. Three basic hypotheses were treated mathematically: there is no functional relationship between true ability and guessing success;…

Three aspects of organization -- structure, resources, and leadership attitudes -- were examined in a longitudinal study of 16 health and welfare agencies to determine which factors best predicted the rate of program innovation. Study results revealed that occupational specialization was the strongest structural predictor, that professional…

A pilot study investigated the role of one response index (specifically, subject's ratings of their spelling accuracy) that was presumed to be predictive of the amount of practice needed to acquire the spelling of a word and gathered data relevant to the nature of practice needed on a word. The study was conducted to aid in the design of a…

To test the predictive efficiency of the Holland Occupational Classification and the related hypotheses concerned with occupational achievement and stability of career from Holland's theory of careers, the classification was applied to a national sample of 973 male retrospective work histories. Analyses were performed by organizing and…

A definition of a suppressor variable is presented which is based on the relation of the semipartial correlation to the zero order correlation. Advantages of the definition are given. (Author/JKS)

The distribution of males and females on a job, occupational classification, and job content were examined as predictors of job sex stereotypes in two studies. Results indicate that the base rate of males and females in the job is the most important predictor of job sextypes. (Author)

The relationship between quantitative predictor variables and the probability of occurrence of one or more levels of a qualitative criterion variable can be analyzed by quantal response techniques. This paper presents and discusses two quantal response models, comparing them to multiple linear regression and discriminant analysis. (Author/JKS)

A suppressor variable is a regressor in a multiple regression which contributes more to the squared multiple correlation than the magnitude of its simple correlation with the outcome variable. An example of such a situation is provided for teaching purposes. (JKS)

Male students worked under a supervisor who was male or female, autocratic or democratic, and possessed a sex-role congruent or incongruent job title. For female supervision only, the more traditionally incongruent the situation, the more unfavorable were the verbal reactions elicited. Task performance and written evaluation of the supervisor were…

Three personality measures were administered twice each with an interval of four weeks between administrations, and the response consistency of these tests was analyzed. The evidence is equivocal. The confounding of consistency effects with other sources of variance remains a problem. (Author/CTM)

After 1 year in the Auburn University School of Pharmacy, 77 students were analyzed to determine: what variables may reliably predict academic success, with success being defined as grade point average; what effect the PCAT has on predicting academic success; and whether a quantitative formula should be used to calculate probable success. (SW)

Information available from birth certificates was used to preduct the psychological and educational status of approximately 1,000 randomly sampled first-grade children. (Author)

A method for studying relationships among groups in terms of categorical data patterns is described. The procedure yields a dimensional representation of configural relationships among multiple groups and a quantitative scaling of categorical data patterns for use in subsequent assignment of new individuals to the groups.

Examines the effects of consensus information on the prediction of behavior as a function of social desirability of consensus information and the presence or absence of vignette information about target persons. Discusses the different manners in which consensus information can be used. (Author/RK)

A semantic differential instrument was devised to predict success of counselor-trainees in a practicum course. The instrument was not useful in predicting success. (Author/JKS)
