Describes a menu-driven software system for searching CD-ROM databases that also unobtrusively gathers data on CD-ROM usage. The discussion covers the steps involved in creating a log file using DOS, tips for capturing user status, strategies for salvaging incomplete data, and types of CD-ROM usage analysis supported by these data. (three…

This article describes a system based on the Epson HX-20 used for real time (rather than time-sample) recording of behavior observation data, which allows the researcher additional options in analysis. Examples of the programs developed, types of research questions asked, and data analyses conducted are provided. (Author/PB)

Presents a system of software and analysis for the development of mathematical models designed to explain the structure in large bibliographic data sets. The discussion covers the goodness of fit obtained in testing and replications, and the implications for the control of large information systems. (six references) (CLB)

The author compares life-cycle data from a retrospective marital history with those derived for the same individuals from panel information. Results indicate that when a marital event is reported in both sources there is substantial agreement about the date of the event. (CH)

Examines fourth-grade students' responses to a performance-assessment task in which students are engaged in exploring data. Includes an "Eating Patterns" task. (MKR)

Describes a school project to choose a mascot in which students learned about sampling and polls while collecting, organizing, and analyzing data. (MKR)

Discussion of retrieval overlap and relevant overlap focuses on an analysis of data from an earlier study on overlap among document representations. This new analysis investigated the odds that an item was judged relevant when it was retrieved by two search fields as opposed to being retrieved by only one field. (Contains 17 references.) (LRW)

Presents the theoretical aspects of a data analysis methodology that can help transform sequential raw data from a database into useful information, using the statistical analysis of patents as an example. Topics discussed include relational analysis and a technology watch approach. (Contains 17 references.) (LRW)

Three dozen observations and recommendations concerning the activities of research consultants in the behavioral sciences are listed and discussed. These guidelines, some stated as aphorisms, are discussed in the categories of planning; implementation; analysis; interpretation; and reporting. (Author/SLD)

Research with couples requires measurement and data analytic techniques extending beyond those typically used with individuals. Measurement issues in couples' research that influence subsequent approaches to data analysis are reviewed, with emphasis on issues of nonindependence in couples' data. Univariate and multivariate analyses of…

Presents research into the quality of data analysis in practical activity in science using information technology. (Author)

Examines consistency of results and variables that may confound validity in child sexual abuse cases. Concludes that the ways in which information on the incidence and prevalence of child sexual abuse has been collected, analyzed, and reported have been flawed to the extent that few reliable conclusions can be made. Includes suggestions for…

Reanalyzes H. Thomas's 1980s data, which used teaching group as the unit of analysis and illuminated some institutional disparities in provision of General Certificate of Education (GCE) A-levels. Uses multilevel analysis to focus on individual students in a hierarchical framework. Among the study institutions, school sixth forms appear less…

A formal model is presented of the statistical properties of molecular behavioral matching. The model indicates that aggregation effects should be controlled in analysis of matching and that comparison of molecular theories of matching performance affords ideographic analysis of choice behavior. (SLD)

Presents a method for the collection and analysis of collateral data about research subjects (i.e., measurements of events in subjects' lives that may affect outcome measures and/or lead to attrition). A six-step procedure evaluates bias resulting from subject attrition from a study using data from lost and retained subjects. (SLD)
