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…

Nine different self scales, along with the corresponding ratings on the same traits by peers and adults, were administered to children and adolescents. With a multitrait-multimethod matrix formulation, the results indicated general differentiation on the nine scales, suggesting situation-dependent and divergent self-pictures. Interpersonal…

Linear classification functions (LCFs) arise in a predictive discriminant analysis for the purpose of classifying experimental units into criterion groups. The relative contribution of the response variables to classification accuracy may be based on LCF-variable correlations for each group. It is proved that, if the raw response measures are…

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…

The village of Tununak on Nelson Island in southwestern Alaska was the site of this field investigation into Eskimo children's games. The focus of investigation was the relationship between role structure in the community and player organization in games; the expressive nature of games as defined by specific values reflected in games and game…

SOME MACHINE-PRODUCED INDEXES ARE COMPARED TO ASSIST IN DECIDING ON THE FORMAT FOR A PROPOSED INDEX. THE OBJECTIVES OF AN INDEX AND THE SEARCH PROCEDURE ARE ANALYZED, AND AN EXPLANATION AND A RELATIONSHIP IS GIVEN FOR KEY-WORDS-IN-TITLE AND KEY-REFERENCES OF THE SAME ARTICLE. BASED ON THE COMPARISON OF THE INDEXES, A 53- YEAR CUMULATIVE INDEX WAS…

Study objectives were to: determine the range of retail goods provided by different size urban places in two predominantly different rural states (Illinois and Iowa); investigate the relationship of distance to larger urban places and the impact on retail offerings of small towns; estimate the effects of location (i.e., proximity) and town size on…

The method of organization in free recall in the form of either clustering or subjective organization is explored in this study. This is just one of the possible forms of retrieval that may be employed. Other possibilities include serial recall, alphabetization, and imagery. To the extent that subjects employ such other strategies, correlations…

Utilizing an ex-post-facto experimental design, all occupied households located within the rural area of Canton San Carlos in Costa Rica (La Fortuna) were studied in August of 1972 for purposes of testing the hypothesis that electricity use is positively associated with level of living. Interviews with 452 heads of households (when possible)…

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…

A new, objective measure of departmental performance--rate of publication in key journals--is described and shown to be highly correlated with the American Council on Education (ACE) ratings of quality. Updated rankings of mathematics, physics, and chemistry departments based on this index are presented. The analyses indicate that the ACE rankings…

A conventional test and two forms of a stradaptive test were administered to thousands of simulated subjects by minicomputer. Characteristics of the three tests using several scoring techniques were investigated while varying the discriminating power of the items, the lengths of the tests, and the availability of prior information about the…

This study compared three approaches to the two-factor experiment with repeated measures on one factor: (1) the conventional mixed model analysis of variance, (2) the Greenhouse-Geisser conservative analysis of variance, and (3) multivariate extensions of analysis of variance. Computer simulated data were used in a total of 96 sets of covariance…

The purpose of this study was to analyze data collected from participants in the Pennsylvania Governor's School for the Arts (PGSA) in terms of their relevance to science education. Its objective was to investigate relationships between variables common to the arts and sciences as a means for hypothesizing alternative approaches for growth in…
