The first author set out to design and secure funding for an hypothesis-based program in a public school setting. The natural history of what happened to that study as it proceeded from design, to funding, to actual implementation, to final reporting serves as the case history of two idealistic evaluators' wildest nightmares.

The proposition that Appalachian religion persists because it is performing a significant function as a mechanism helping the adjustment of people who due to modern changes, have become dislocated socially, economically, and psychologically was tested. Religiosity was defined on the basis of 4 variables: (1) religious beliefs; (2) need to use…

A procedure for predicting categorical outcomes using categorical predictor variables was described by Moonan. This paper describes a related technique which uses prior probabilities, updated by joint likelihoods, as classification criteria. The procedure differs from Moonan's in that the outcome having the greatest posterior probability is…

The Rasch item analysis model is supposed to yield norm-free estimates of ability and easiness values, but there are several possible interpretations of the nature and extent of such norm-freeness. One such interpretation was that to involve the scores of one single experimental group of testees which were embedded in four differently skewed…

There is increasing debate over the unidimensionality of the construct "drive" in theories of behavior. The earliest drive theory postulated a simple entity which increased or decreased as a function of external or internal stimulation and affected behavior monotonically. Duffy and Malmo have recently hypothesized that the effects of…

The purpose of this study was to develop the Johnson-Neyman Procedure (JN-Procedure) appropriate to multiple groups and covariables, and demonstrate its use in the analysis of group differences. A sequence of significance tests which makes it possible to identify the most parsimonious analysis of group differences appropriate to a given set of…

Family-physician relationships were examined in terms of solo vs group physician practices in two rural southern counties of different socioeconomic status. Comparatively speaking, County B was poorer, had a much higher representation of blacks, had lost considerable population during 1960-70, depended to a much lesser degree on manufacturing, and…

A group of students normally distributed in aptitude and given the same instruction will produce a normal distribution of student achievement. It has been contended that if each of five primary variables in learning are optimized for each student, all students should be expected to achieve mastery of the material. These variables are (1) aptitude…

A major variable by which national educational systems may be compared is their structural differentiation, defined (1) as a process, referring to the multiplication of one structural element into two or more structurally distinct elements; and (2) as a state, referring to the number of structurally distinct elements which exist in a system at a…

This study was conducted to explore the idea that the Negro dialect operates as a source of interference in the acquisition of reading skills by Negro children. Two first grade classes from an Oakland, California, inner city school were chosen to participate in this experiment. The pupils were all pretested. Half of them were then randomly chosen…

This study investigates three hypotheses: (1) there is a positive relationship between maternal satisfaction with substitute child care and maternal work satisfaction; (2) there is no relationship between satisfaction with substitute child care and the quality of mother-child interaction; and (3) there is a positive relationship between maternal…

The purpose of this study was to: (1) investigate the use of special education services in grades 1-3 by 48 children who had attended Head Start, (2) to investigate the use of special education services by a matched group of 48 children who were eligible for but had not attended Head Start, and (3) to compare the differences between the two groups…

This study was undertaken to investigate approaches fifth grade children of similar mental ability follow when writing narrative compositions, to identify procedures unique to good and poor writers, and to observe sex differences relative to quality of written expression and ability to verbalize concerning the writing process. A sample of 230…

This paper relates educational and psychological statistics to certain "Research Statistical Tools" (RSTs) necessary to accomplish and understand general research in the behavioral sciences. Emphasis is placed on acquiring an effective understanding of the RSTs and to this end they are are ordered to a continuum scale in terms of individual…

This study, designed to explore the differences in the experiences of white and Negro workers in obtaining and retaining employment in the white-collar labor market, utilized an extensive questionnaire and structured-interview techniques. A survey was made of a random sample of 250 respondents (164 whites, 83 Negroes, and 3 Others) from three…
