Use of analysis of covariance or multiple regression can lead to Type I errors in pretest-posttest nonequivalent control group designs. Analysis of the interaction term of a repeated model analysis of variance was shown to help identify areas of significant change. The standardized difference score, effect size, suggested meaningful differences.…

Four methods are outlined for estimating or approximating from a single test administration the standard error of measurement of number-right test score at specified ability levels or cutting scores. The methods are illustrated and compared on one set of real test data. (Author)

This paper discusses measurement and statistical issues raised by Title IX requirements on selection and admission procedures. Admission procedures treating males and females identically may be unfair to female applicants. Recommendations concerning implementation of studies to evaluate an institution's current admission procedures will be…

Study report of some evidence on the verification of participant evaluation. Results suggest that the participants' evaluation of adult education programs could be an effective tool for the development and refinement of future programs. (Author)

Patterns of functional and size differentiation among local organizations may be seen as the result of basic structural properties of the community. The principal goal of this paper is to examine certain conditions promoting differentiation on these dimensions. (Author/EB)

In the study reported, the labor force characteristics of the nation's 16.2 million teen-agers (aged 16 to 19) are reviewed and evaluated for three types of area: central cities, suburban rings, and nonmetropolitan areas. Tables give data on teen-age employment and unemployment, comparing sex, race, and occupational groups. (Author/AJ)

Describes a series of user studies used to advance understanding of how people use electronic tables (E-tables) and inform the development of a Web-based statistical table browser for use by non-specialists. Results of needs assessment, prototype development, and user studies provide a foundation for understanding E-tables in general and guiding…

The three standard-setting approaches described in this special issue are summarized and contrasted: (1) judgmental policy capturing; (2) the extended Angoff method; and (3) the dominant profile method. An integrative summary of findings is followed by recommendations for modifying the methods. (SLD)

A modification of a test of the equality of nonindependent alpha reliability coefficients is proposed. It avoids the limitation that the product of the number of test parts times the number of subjects be quite large. Monte Carlo studies indicate that this test can be used in comparing interrater reliabilities. (SLD)

I take issue with several points in the Howleys' reanalysis (Vol. 12 No. 52 of this journal) of "High School Size: Which Works Best and for Whom?" (Lee & Smith, 1997). That the original sample of NELS schools might have underrepresented small rural public schools would not bias results, as they claim. Their assertion that our conclusions about an…

Norm setting has been shown to be a crucial element of effective drug education. The purpose of this study was to examine the degree to which a videotape describing concepts and methods for establishing positive norms would enhance standard training. Participants included 35 teachers and 64 health education students who were randomly assigned to…

The National Longitudinal Surveys (NLS), sponsored by the Bureau of Labor Statistics, U.S. Department of Labor, are a set of surveys each of which has gathered information at multiple points in time on the labor market experiences of five groups of men and women since the mid-1960s. Each group of at least 5,000 persons was selected to be…

Studying the process of change becomes tricky from a methodological point of view if change has its origin in both the intrapersonal and societal spheres. This paper examines the problems which arise when discussions of change measure only changing means without considering the fact that constructs of change are continually redefined. For example,…

Two analyses of variance (ANOVA) models for item scores are compared. The first is an items by subject random effect ANOVA. The second is a mixed effects ANOVA with items fixed and subjects random. Comparisons regarding reliability, Cronbach's alpha coefficient, psychometric inference, and inter-item covariance structure are made between the…
