The Concise Data Processing Assessment (CDPA) was developed to probe student abilities related to the nature of measurement and uncertainty and to handling data. The diagnostic is a ten question, multiple-choice test that can be used as both a pre-test and post-test. A key component of the development process was interviews with students, which…

Social scientists usually are more interested in consumers' dichotomous choice, such as purchase a product or not, adopt a technology or not, etc. However, up to date, there is nearly no model can help us solve the problem of multi-network effects comparison with a dichotomous dependent variable. Furthermore, the study of multi-network…

A general purpose computer program for the calculation of a matrix of tetrachoric correlations is described. This program was developed for use in adaptive (and other) testing research for examining the unidimensionality assumption in latent trait theory, in conjunction with available factor analysis programs. Several other potential applications,…

With no previous training in data processing, a teacher can set up a computer scoring program for objective test materials that will save many hours of manual work in test correction, scoring, ranking, and item analysis. Teachers, school administrators, and counselors can employ statistical information contained in computer printout sheets to plan…

A series of computer programs to handle natural language retrieval and analysis in a manner analogous to that of a statistical package is discussed. The document presents an overview of several language analysis projects currently underway, and of several research approaches to problems in language analysis. The manner in which the Language…

This guide to ERRATA, a set of HyperCard-based tools for response analysis and error diagnosis in language testing, is intended as a user manual and general reference and designed to be used with the software (not included here). It has three parts. The first is a brief survey of computational techniques available for dealing with student test…

When survey data are analyzed by computer, a codebook is necessary to show how raw scores are translated to computer-usable form. When data are tabulated by hand, the need for a codebook depends upon the number of respondents, the number and complexity of items, and the types of statistical manipulations required. During the process of coding,…

The Language Analysis Package (LAP) was developed by the Southwest Regional Laboratory (SWRL) to assist researchers in the analysis of language usage. The function of the KWIC (Keyword-in Context or Concordance) Module of the LAP is to produce keyword listings from the input text being analyzed. Such listings will contain location information…
