Four recent indices emphasizing the interrelationships of score distribution shape, modality, mean, and variance were investigated to determine the reliability of mastery tests. Attention was focused on the values of the indices when the cutoff score was near to or far from the modes of distribution. Five types of score distributions were…

Subjects dealt with in this report include: (1) team teachers dealing with complex materials; (2) career education programs that expose students to the world of work; (3) research and development outcomes relating to publications on drugs, cooking, cognitive development, early education programs, consumer education, and math teaching; (4) special…

Having the SCAT V and Q percentile scores for 308 of the 504 students enrolled at Maui Community College (Hawaii) in the 1967 fall semester, a statistical test was made to determine whether or not a significant percentage of the students had scored at or below the 50th percentile. By categorizing students according to their areas of study--liberal…

The amount of variance accounted for by treatment can be estimated with omega squared or with the squared multiple correlation coefficient. Monte Carlo methods were employed to compare omega squared, the squared multiple correlation coefficient, and the squared multiple correlation coefficient to which a shrinkage formula had been applied, in…

The U.S. Army Research Institute for the Behavioral and Social Sciences has developed a wide range of statistical models to test hypotheses generated in relation to an equally wide range of measurement and evaluation situations. The randomized block (RB) design has traditionally been a preferred model for much psychological research. The RB has…

Using "Books for College Libraries" as a standard reference against which to compare the Purdue University Calumet Campus library collection, a quantitative analysis of the library's holdings in various subject areas was done during the 1973-74 academic year. For each of the 65 subject areas selected, randomly chosen entries in…

Cuyahoga Community College (Ohio) conducted this statistical study of community-junior colleges' academic policy concerning the elimination of academic dismissal and failing grades. To obtain data, a sample of 100 institutions was selected from the 698 regionally accredited junior colleges. Percentage representation in the sample was based on the…

This book on the growth of word meaning in children focuses on the development of the appreciation of the relations that exist among twenty selected words as the individual matures from childhood through adolescence to adulthood. The four preconceptions which determined the experimental tasks, the set of words used, and the methods of analysis…

The transferability, quality, and student perception of biology instruction at Metropolitan Campus, Cuyahoga Community College (Cleveland, Ohio) were the data sought in this joint study performed by the College's Department of Biology and the Office of Institutional Research and Studies. All Students who completed Biology 112 in the 1967-68…

The dissertation explores criteria for evaluating the performance of trigger mechanisms for determining extended benefit payment periods. A review of the current law is made as well as a brief summary of legislation leading to its passage. A quantitative model using concepts from the Theory of Markov Chains is established which meets established…

Press coverage of a suburban midwest school district is analyzed as a set of time series of observations including the amount and quality of coverage. Possible shifts in these series because of the emergence of controversial issues are analyzed statistically using the Integrated Moving Average Time Series Model. Evidence of significant shifts in…

The applicability of the Analysis of Variance, ANOVA, procedures to the analysis of dichotomous repeated measure data is described. The design models for which data were simulated in this investigation were chosen to represent simple cases of two experimental situations: situation one, in which subjects' responses to a single randomly selected set…

This is one of a series of eight short monographs intended to aid practicing educators in planning and conducting accountability programs in schools. This booklet discusses how to select a statistical technique that is appropriate to the objectives of a particular research or evaluation effort. Short sections focus in turn on classifying a study,…

Describes the renormalization group theory of second-order phase transitions suitable for undergraduate statistical physics. (Author/GA)

This is the first of a series of articles on the Vietnamese who have come to the U.S. since 1975. It deals with the making of the refugees and describes how the negative motivations and regrets with which they have come may act as obstacles to their adjustment to American life. (Author/GC)
