This self-contained and self-instructional unit is intended for use by evaluation and development personnel and by students in introductory research and evaluation courses. The unit contains a discussion of the regression employing graphic illustrations with actual data. The user is introduced to the regression effect in the single group…

The relative precision of four methods of estimating missing data in principal components analysis was investigated. Artificial data with known characteristics, obtained from Cattell's "Plasmode: 30-10-4-2," was used with one third of the data on half of the variables being systematically eliminated. The four methods of missing data estimation…

This report presents the methodology for short-run forecasting of personal income and employment in Hawaii. The econometric model developed in the study is used to make actual forecasts through 1973 of income and employment, with major components forecasted separately. Several sets of forecasts are made, under different assumptions on external…

As the first step in a program to develop quantitative techniques for prescribing the design and use of training systems, the present study attempted: to compile an initial set of quantitative indices, to determine whether these indices could be used to describe a sample of trainee tasks and differentiate among them, to develop a predictive…

This study was concerned with various schemes for reducing the number of variables in a multivariate analysis. Two sets of illustrative data were used; the numbers of criterion groups were 3 and 5. The proportion of correct classifications was employed as an index of discriminatory power of each subset of variables selected. Of the four procedures…

To identify the determinants of satisfaction for managers, a Decremental Stepwise Multiple Regression analysis was run on the exempt employees in five companies. There were 27 predictor variables, each reflecting satisfaction with some specific aspect of work. The variable to be predicted was global satisfaction. It was expected that the…

To predict the educational quality of programs in 150 school districts, this study used 34 predictor variables in a multiple regression analysis. Dependent variables used to represent educational quality in a district were (1) the percent of rejections by the local Selective Service Boards for mental reasons, (2) the percent of elementary and…

This review was undertaken to organize and present the findings of educational production function research by educators and economists. A summary of these findings could be a valuable aid in the educational decision making process, especially to administrators working in local school districts. Research of this type concentrates on determining…

The development of a scale for measuring the interaction of Mexican Americans with Anglos (Anglo Interaction Index) was discussed. The scale was part of a larger investigation on status mobility among middle-class Mexican Americans in Texas. Data was collected in Waco (selected for pretesting), Austin, McAllen, and Lubbock. These communities were…

The major objectives of this study were: to determine whether information feedback provided during a difficult task would reduce State-Anxiety (A-State) and whether learner control of feedback would lead to further reductions in A-State. Another objective was to attempt to bridge cognitive and affective domains by examining relationships of the…

The author's previously developed theory on income distribution, in which two of the explanatory variables are the average level and the distribution of education, is refined and tested on data selected and processed by the author and data from three studies by Americans. The material consists of data on subdivisions of three countries, the United…

Provided is the description of a program planning and assessment process model which is technically based on multi-variate analysis and can be used to evaluate special education programs. The model is noted to be divided into four sections: (1) specification of program objectives, (2) pre-assessment procedures, (3) evaluation methodology, and (4)…

An attempt to explain apparent differences between residents of larger and smaller communities. Twenty years of Gallup Poll data on social attitudes were examined. Results suggested that innovations emerge in metropolitan centers and diffuse to smaller areas, thus a gap always exists. (Author/BC)

It appears that definitions of "adult" that invoke notions of social role as the central explanatory construct are well-founded. At present it appears that roles (and their associated experience) account for about 50 percent of the variance in attitude change; historical events might account for the other 50 percent. Available from:…

The relationships between academic achievement in medical school and performance in first-year residency was investigated. Residents rated as "outstanding" consistently performed better on the National Board of Medical Examiners' examinations than those rated as "below average." Results support the consideration of academic…
