Proposes an alternative methodology for handling queries with weighted search terms or search criteria in a fuzzy environment as a means of improving the performance of information retrieval systems. (EM)

Results of an investigation designed to determine whether the impact factor or the immediacy index--two derivative measures of citation analysis--provide useful insights into qualitative relationships among scientific journals indicate that neither measure is significant. (MBR)

The paper reviews a series of models designed to reduce bias in the assessment process and describes the intent of each model and their interactive effect in the process of nonbiased educational evaluation. (Author/CL)

Discusses the use of the chi-square statistic in educational evaluation based on the assumption that the availability of calculators and computers does not absolve educators from the responsibility of understanding this statistically evaluative technique. Illustrates applicability to an action research study in a middle school setting. (NEC)

A dialog between two fictional teachers provides some basic examples of how research that uses approved methodology may provide results that are significant statistically but not significant practically. (PGD)

The second half of a dialogue between two fictional teachers examines the significance of statistical significance in research and considers the factors affecting the extent to which research results provide important or useful information. (PGD)

Uses principles of latent trait theory to derive conditions under which mean differences between groups on an observed variable are in fact indicative of mean differences on an underlying construct. Pays particular attention to the logistic curve as a model for describing the relation between the observed variable and the construct. (Author/CB)

This article describes the strengths and weaknesses of different models of classification (primarily monothetic and polythetic) and then focuses on cluster analysis as a method of pursuing a polythetic model. Design features that need to be incorporated in a cluster analytic study are discussed in relation to theory formulation, internal validity,…

Acquiescence, or acquiescent responding, is reviewed. A detection method using the concept of differential person functioning is illustrated with two data sets. The effects of acquiescence are shown to be different for each example. Implications for questionnaire and attitudinal scale development are discussed and an operational definition for…

The goal of college preparation programs is to help students, particularly underrepresented students of color, to enroll and succeed in college. While many programs focus on strengthening students' math and reading skills, familiarizing them with college entrance exams, and demystifying the college admissions process, there are few guidelines for…

Mixed methods research has increased in popularity over the past 20 years. Literature reveals that exploratory qualitative analysis followed by confirmatory survey research is common and concurrent studies outnumber longitudinal design. Longitudinal studies using quantitative and qualitative methods in sequence for exploratory purposes are rare,…

The usefulness of meta-analysis in summarizing domains of primary research has led to widespread use of the techniques. Often, however, the researcher will have several options when cumulating empirical studies and readers will have questions regarding judgment calls made during a meta-analysis. In these cases, it is helpful to consult the primary…

An introduction to Fortran programming specifically for social science statistical and routine data processing is provided. The first two sections of the manual describe the components of computer hardware and software. Topics include input, output, and mass storage devices; central memory; central processing unit; internal storage of data; and…

Although there is extensive literature on interpersonal influence in counseling, there are few studies of the relative influence of counselors on clients and clients on counselors. To investigate the convergent validity of three statistical approaches to relative influence in counseling, 57 counseling interviews were analyzed. The three…

Several developments in the use of the new method of meta-analysis give cause for optimism. First, different meta-analysts are doing work in the same areas, leading to increased confidence in meta-analytic results. Second, meta-analysts are beginning to include raw data in their reports, which helps readers pinpoint the exact studies that lead to…
