Examples of the use of Multiple Linear Regression (MLR) techniques are presented. This is done to show how MLR aids data processing and decision-making by providing the decision-maker with freedom in phrasing questions and by accurately reflecting the data on hand. A brief overview of the rationale underlying MLR is given, some basic definitions…

This study reports an attempt to explore within a heterogeneous population the pattern of influence which selected maternal traits exert on internal locus of control at age 5 years. Information on the relevant variables was retrieved from the computer-based data bank of the St. Louis Baby Study. The maternal traits used for prediction included the…

The applicability of a mathematical theorem designed to trace causality of a three-variable path that consists of an initial cause variable, an intermediate variable, and a final-effect variable with control over other system variables is evaluated. The formula was used with a horizontal rather than a normal distribution, as had been done in an…

This is a report of an extensive follow-up study of Lake Land College transfer students at Eastern Illinois University. An analysis of their grade point average (GPA) term by term reveals a drop in GPA the first term after transfer and subsequent recovery. This phenomenon, known as "transfer shock," is compared with results obtained in…

This study examines the determinants of youth labor force participation, school activity, and employment rates. Nearly all the data came from the March 1967 Current Population Survey, both from survey results and from the individual data records collected in the survey. After records were obtained for 104,000 individuals, of whom 14,000 were…

Methods exist for testing the homogeneity of group regression for the case in which there is only one predictor. Studies which have investigated aptitude-treatment interactions have adopted the homogeneity of regressions test as standard methodology for assessing the difference in regression slopes across treatments. Additional statistical…

This study focuses on the economic benefits derived by the migrant from migration. The report presents a methodology for computing monetary benefits, an estimate of these benefits, and implications of the findings for public policy. Included are a discussion of domestic migration and public policy, an economic theory of migration, an explanation…

Individualized instruction presents problems in measurement which challenge the conventional measurement paradigms. Measurement techniques must take into consideration the problems of item variance characteristics of computer-assisted instruction (CAI), idiosyncratic learning sequences, and lack of a model for effectiveness assessment. The…

The Torrance Tests of Creative Thinking (TTCT) may represent a breakthrough in the area of creativity research, since they provide a functional instrument for measuring creative potential in children, adolescents, and adults. However, there are certain technical problems with achieving interscorer reliability which may act as a deterrent to the…

The unbiased estimate of a "treatment effect" reached by analysis of covariance in a nonrandomized experiment would often require that a different covariate be used in each treatment. A sufficient but unlikely condition for an unbiased estimate is that the covariate for each treatment is (1) the complete covariate that predicts the outcome as…

This annual report presents data on bond elections and bond sales for financing the construction of public elementary and secondary school facilities. Data, summarized by state, are presented in tables and charts containing information on the number and dollar value of bond issues voted on and passed, and the number, dollar value, and net interest…

The optimum weighting of variables to predict a dependent-criterion variable is an important problem in nearly all of the social and natural sciences. Although the predominant method, multiple regression analysis (MR), yields optimum weights for the sample at hand, these weights are not generally optimum in the population from which the sample was…

By using complex multiple regression models to generate regression surfaces, the relationships between academic achievement, creativity, and intelligence are examined. Findings indicate that for certain academic subjects creativity is related to achievement up to a threshold level of intelligence, but after the threshold has been reached…

Work values as an exploratory construct in vocational choice supplemental to inventoried and expressed vocational interest was examined using 42 ninth graders. The demonstrated utility of work values suggest using work values to facilitate decision making with the vocationally decided, omitting the use of interest inventories. (Author)

Survey data from a sampling of Alabama high school seniors showed that female students were significantly more likely to use all sources of occupational information than males, and students in the college preparatory program more so than those in the general program. (MF)
