Several advantages to the use of factor scores as independent variables in a multiple regression equation were found. To help select the most desirable type of factor score on which to calculate a regression equation, computer-based Monte Carlo methods were used to compare the predictive accuracy upon replication of regression of five…

To the data analyst, outliers can present both a problem and an opportunity. Stray or outlying observations can severly distort estimates of a distribution's central tendency (like the mean) and estimates of one variable's relationship to another (like the regression coefficient). These problems are frequent and serious, and as a result,…

Reported research uses stepwise multiple regression analyses to generate regression equations for 60 school age subjects with choice of right action and stage of moral reasoning on moral dilemmas as the dependent variables. Age, IQ, socioeconomic status, awareness of consequences, empathy, and mean moral maturity scores were used as predictor…

The results of an algorithm which is designed to take a set of commonality coefficients, either real or manipulated, and, if possible, produce one or more sets of regressor correlations that are consistent with them are examined. A number of different ways of resolving the higher order commonality values into their lower orders were tried and the…

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)
