In the study "Public and Private Schools," the conclusions by James Coleman and others that private schools produce higher test scores and do so by employing certain school policies are not valid because the methods and interpretations used in the analysis fall below the standards for social-scientific research. Moreover, the conclusions…

The Evaluation Office of the Seattle Public Schools is currently engaged in a project that uses student test performance to identify educational program characteristics associated with academic gains. Methods used to develop an index of academic gains are described, and one method that best fits the following criteria was selected. It should be:…

A study was conducted to determine if students who depend on an analytical cognitive style will learn more when matched with a step-by-step treatment, and whether students who depend on a holistic cognitive style will learn more when matched with an all-at-once treatment. To test these hypotheses, scores on the Wechsler Verbal Similarities Test…

An experiment, which replicates an earlier study conducted in Sweden, was performed to study the effects of prior knowledge of relevant subject matter on reading comprehension and on memory. Fifty college students read one of two contrasting passages that presented two opposing points of view after they had recorded their beliefs about the subject…

This research was designed to identify and assess the effects of a job's context and naturally occurring job content changes upon the job attitudes of 709 Air Force radio operators. The first of two phases of the investigation identified specific job types within the radio operator career field at two points in time, and determined the flow of…

Demographic data on 92 subjects identified as having reading problems were used to develop equations useful in identifying high risk, reading disabled students. Multiple linear regression analysis of the data indicated that reading disability (1) had a significant positive relationship with birth order and number of siblings; (2) had a positive…

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…
