Discusses substantive scale construction and the need for Rasch measurement practitioners to give careful consideration to designing variables based on theory, item construction, and models for the analysis of data. (SLD)

Describes a knowledge management system that was developed to help provide structure for dynamic and static data and to aid in the analysis of complex experimentation. Topics include quantitative and qualitative data; mining operations using artificial intelligence techniques; information architecture of the system; and transforming data into…

Discusses students' exploration of a particular rational function in the context of people waiting in line for service. The concepts of domain, range, and asymptotes are also developed in that context as is the effect of changes in input variables on function outputs. (Author/NB)

Describes a process for teaching nursing research via secondary analysis of data sets from the National Center for Health Statistics. Addresses advantages, potential problems and limitations, guidelines for students, and evaluation methods. (Contains 32 references.) (SK)

Discusses the theory and practice of case study analysis and its appropriateness as a method for technology education research. Describes how to identify suitable problems, conduct literature reviews, and analyze and interpret cases. (Contains 60 references.) (SK)

The stability of dimensions extracted from a body of free response data was studied using 1,523 expressions of concern and questions raised by 271 elderly persons and analyzed by 2 groups of experimenters. The structures of resulting multidimensional configurations obtained by the 2 groups were identical. (SLD)

Notes that family researchers are increasingly using panel data to investigate family processes. To aid family researchers in understanding panel analysis, focuses on two panel analysis strategies--structural equation model techniques and methods of event history analysis. Several additional methods of analyzing panel data are also briefly…

Envisages possible enhancements in labor force data collection, analysis, and dissemination, with expansion of both household and establishment surveys and greater use of administrative data. (Author)

Articulates a case for triangulation as a research strategy to aid in the development of theoretical claims and the integration of theory. Demonstrates the potential and actual uses of these types of triangulation for argumentation by examining research in everyday argument and argument fields. (MS)

A class of multinomial models for source monitoring is developed and evaluated. These models are capable of taking data from source-monitoring models and separately measuring the cognitive capacities that underlie such data. Usefulness of the models is demonstrated with published data from areas of reality monitoring and bilingual memory. (SLD)

The power of randomization tests was systematically examined through simulation for typical designs that rely on the random assignment of interventions within the observation sequence. A 30-observation AB design, 32-observation AB design, and multiple baseline AB (15 observations on 4 individuals) were studied. Power estimates were generally found…

A general approach is described for the analysis of categorical data when there are missing values on one or more observed variables. The method is based on generalized linear models with composite links. Situations in which the model can be used are described. (SLD)

Reviews methods for analyzing outcome data when some data are missing. Presents approach for comparing outcome results in two-group, randomized design with missing data. Proposed analysis is based on concept of "modeling our ignorance" by examining all possible outcomes, given known number of missing results with binary outcome, and then…

Presents strategy for analyzing interdyadic differences in sequential data on social interactions. Shows how to statistically describe interactional structure within each dyad governing stream of that dyad's social interactive behavior and how scores describing dyadic structures can be related to covariate information about dyads. (Author/NB)

A procedure is presented to transform an n-dimensional scatter diagram into a two-dimensional scatter diagram while preserving proximity relationships between points. This procedure can help in the presentation and interpretation of multivariate results. (Author/SLD)
