Like performance-enhancing drugs inflating apparent athletic achievements, several common social science practices contribute to the production of illusory results. In this article, we examine the processes that lead to illusory findings and describe their consequences. We borrow from an approach used increasingly by other disciplines--the norm of…

The central purpose of the present study was to evaluate several statistical techniques (analysis of variance (ANOVA) on raw gains, standardized ANOVA, standard analysis of covariance (ANCOVA), and z-score ANOVA) under various quasi-experimental conditions (three levels of reliability, three levels of sample size, three levels of gain, and the…

Delineates various levels of theory with implications for research in library and information science. Based upon a review of literature on theory building and research methods in the social sciences, a model is proposed which displays a taxonomy of theory in hierarchical form. (EM)

Although the primary responsibility rests with the authors of articles reporting nonsignificant results to demonstrate the worth of the results by discussing the power of the tests, consumers should be prepared to conduct their own power analyses. This article demonstrates the use of power analysis for the interpretation of nonsignificant…

Using a Monte Carlo approach, comparison was made between traditional procedures and a multiple linear regression approach to test for differences between values of r sub 1 and r sub 2 when sample data were dependent and independent. For independent sample data, results from a z-test were compared to results from using multiple linear regression.…

Conceptualizes the process of conducting integrative research reviews as a data-gathering, empirically based procedure and offers guidelines for conducting such reviews. Introduces specific suggestions that were heretofore unaddressed. Maintains that efforts to standardize integrative review process and to ensure its scientific rigor in counselor…

The microcomputer offers social science field researchers a valuable tool for managing qualitative research data. In addition to the flexibility and efficiency of the microcomputer, the logic governing its programming and operation imposes a framework on the research process which necessitates that research decisions and strategies be explicit and…

This report describes the application of a shell expert system from the medical diagnostic system, Neomycin, to Caster, a diagnostic system for malfunctions in industrial sandcasting. This system was developed to test the hypothesis that starting with a well-developed classification procedure and a relational language for stating the…

Histories of media research commonly assume that models of mass media effects have progressed from direct or hypodermic effect models to indirect or multi-step models. Recently, however, B. Reeves and E. Wartella have objected to this assumption. To evaluate their alternative hypotheses, 163 studies from over 88 sources, representing nearly a…

An approach to statistical testing, which combines Neyman-Pearson hypothesis testing and Fisher significance testing, is recommended. The use of P-values in this approach is discussed in some detail. The author also discusses some problems which are often found in introductory statistics textbooks. The problems involve the definitions of…

This study attempted to determine if there was a change in job attitude among employees of a state institution for the developmentally disabled after a move to new, superior facilities. An attitude scale was constructed and administered in December 1982, prior to the move. A second testing occurred two months later, after Experimental Group I had…

This paper examined the rank transformation approach to analysis of variance as a solution to the Behrens-Fisher problem. Using simulation methodology four parameters were manipulated for the two group design: (1) ratio of population variances; (2) distribution form; (3) sample size and (4) population mean difference. The results indicated that…

Develops a theory of mediated learning from practice. Problems inherent in developing theories are reviewed; general assumptions are identified; and a descriptive theory is generated that identifies favorable factors facilitating learning. Factors are checked for consistency and used to generate hypotheses for collecting research data capable of…

Describes study that investigated the communicability of the emotional connotation of various typefaces. Typographers, student instructional technologists, and naive readers (high school and college students) rated 30 typefaces using a semantic differential scale. Seven hypotheses tested are discussed and results are analyzed. (Author/LRW)

Problems involved in providing practical research experience in research methods courses are discussed. The two points in the research process where time is most critical are selecting measures and data collection. This paper suggests using a data base from previous research and having students conduct simulated studies based on randomly selected…
