The purpose of this study was to broaden the aptitude by treatment interaction paradigm. The relationship between memory span and performance in two different transfer conditions was examined, and task involvement and anxiety were considered as they contribute to the relationship between aptitudes and performance.

The technique of analysis of covariance is examined for its relevance to educational and psychological investigations. A study of the arithmetic procedures, history, and statistical properties shows that, though the concepts are relevant to many data collection designs, the customary calculations are often inappropriate. Some suggestions are made…

A model and a computer program for performing conjoint measurement is developed. (AG)

School unit residuals from multiple regression predictions of sixth-grade reading scores were developed for a population of 66 elementary schools, using Dyer's Method II (matched longitudinal data) and Method III (unmatched longitudinal data). The input variable sets were (1) previous achievement data alone, (2) achievement data and nonachievement…

Early procedures for the analysis of multivariate panel data do not rest on well-specified statistical models. Recent approaches based on path analysis suffer from the defects of variable standardization and lack of attention to measurement error. The paper formulates a measurement model for quantitatively scaled multivariate panel data. The model…

Analysis of the voting patterns in six states on the 1976 initiatives for a moratorium on nuclear power plants. Demographic characteristics were found to be unimportant variables, while percentage of people enrolled in colleges and universities, percentage of land in farms, and relative cost of electricity were found to be important. Stresses…

The relationship of sex role acceptance to actual and desired fertility was assessed in a sample of female college students and women's organization members. Multiple regression analysis indicated that behavioral measures of sex role acceptance accounted for more variance in predicting desired fertility than did the Bem Sex Role Inventory.…

Since the Bureau of Labor's cost-of-living statistics are available for only 40 standard metropolitan statistical areas (SMSAs) in four regions, the author presents a method to estimate family budgets for all SMSAs. Data for the calculations are easily accessible in Census and other government publications. (Author/KC)

In this study a new and quantitative approach to analyzing legislature change was applied to the U.S. Senate's change from support to opposition to the Vietnam war. Cumulative war costs, public opinion, and antiwar demonstrations all correlated with Senate roll call outcomes, but were also intercorrelated. General strengths and weaknesses of this…

Using data from the National Longitudinal Survey of women between 1967 and 1971, the author concludes that tax increases have a negative effect on the labor supply of married working women. Among the factors examined were presence of preschool children, husband's approval, home ownership, health, and educational background. (MF)

Success of student nurses from three ethnic groups on a state board certification examination was predicted from study behavior, course grade point average and standardized achievement tests administered prior to nurse training. The achievement tests proved to be the best predictors across groups. (Author/JKS)

Common factor scores were compared to unfactored data-level variables as predictors in terms of the correlation of a criterion with the predicted value in multiple regression equations applied to replication (cross-validation) samples. (Editor)

Data from the National Research Council's Doctorate Records File extract prepared for UCLA indicated that source of support was the most important variable in predicting time to doctorate. Following source of support were postdoctoral plans, number of dependents, sex, and field of study. (Author/MLW)

This study examined the relationship between scholarly publication by faculty teaching in library and information science programs and 18 selected variables. Six variables were found to be predictors of faculty productivity: highest degree earned, size of faculty, years elapsed from bachelors's to highest degree, program type, prestige of program,…

Several methods for dealing with incomplete multivariate data and ways to examine the effectiveness of these methods are discussed. It is concluded that pairwise and listwise deletions are among the least effective methods in terms of approximating the results, whereas estimates based on correlational procedures generally produce the most accurate…
