Three methods that can be used subsequent to a regression analysis to determine the relative effectiveness of schools are Dyer's Performance Indices, Scheffe's hyperbolic confidence bands, and Gafarian's linear confidence bands. These methods were applied to data from 54 hypothetical schools randomly generated from a multivariate normal…

The present paper sought to investigate the usefulness to accountability of identifying outlying schools through multiple regression. The outlier approach identifies schools which differ significantly for reasons other than variation in the predictors. The present study was not able to confirm the construct validity of the outlier approach for the…

This interim report is concerned with the analysis of educational experiments and quasiexperiments where alternative teaching methods are applied to intact classes or where alternative programs are set up in samples of schools or communities. Generally, such studies have used the class, the school, or the community as the unit of sampling with the…

This dissertation considered the experience of various groups that participated in the Job Corps both during and after their stay in Job Corps. Considerable differences were found between the various race/age and race/religion groups considered. All groups, however, received benefits in excess of costs, with the Benefit/Cost ratios found ranging…

Multiple regression analysis is not beyond the reach of most researchers and research classes. It may prove beneficial to the communication researcher for a number of reasons. One of its most significant contributions to effective research is the utility of looking at several variables simultaneously. Another contribution of multiple regression…

To identify and quantify factors which determine the occupational and educational structure of the labor force, the 1960 and 1961 census data of 53 countries were analyzed. Multiple regression analysis showed output per worker and product per capita to be the best explanatory variables for occupational structure. The educational profile of the…

The nature of the relationship between a teacher's knowledge of certain principles of adult teaching, his application of those principles in classroom practice, and the resultant level of satisfaction reported by his adult students was studied. Agroup of 1,596 adults in 100 university classes were the subjects. A theoretical framework adapted from…

This document consists of unrevised lecture notes for the first half of a 20-week in-house graduate course at Rand Corporation. The chapter headings are: (1) Histograms and descriptive statistics; (2) Measures of dispersion, distance and goodness of fit; (3) Using JOSS for data analysis; (4) Binomial distribution and normal approximation; (5)…

This research is based on more than 1,600 school district property tax elections in California from the mid-1950s to 1972. Population, housing, social, demographic, and economic information by school district was available. This large, comprehensive, and consistent data base permitted investigation of the choices of the electorate with respect to…

Five category scores of word usage frequency were generated from responses on the Rotter Incomplete Sentences Blanks for 61 college freshmen. These scores were then used to predict asocial behavior of the freshman. (Author/JKS)

Systematic procedures are outlined for testing the assumption made on the dependent variables in a variety of statistical techniques. Specifically, procedures are outlined for testing the assumption that the dependent variables are measuring the same constructs in the same metrics with equivalent reliabilities across all subgroups. (Author/JKS)

A series of multiple regression analyses was used to investigate a salary equity policy in a statewide system of institutions of higher education. Faculty rank, number of publications, and teaching effectiveness were among the variables examined. (JKS)

Discusses a path analysis of the attitudes of 800 black male and female Americans in Baton Rouge, Louisiana. Their attitude toward their skin color is analyzed as a function of their personal orientation toward political and social separation, whereas both their ratings and their orientation are analyzed as a function of their education, age and…

Evaluation Research Society members (n=160) assessed the attributes of research that produce credibility. The study focused on the acceptability of no-difference findings. Randomization, statistical power, number of measures reported, and equivalent groups were tested to determine their influence on acceptability of both no-difference and…
