Order analysis, a technique to isolate unidimensional hierarchies representing multidimensional structure of binary data, is reviewed. Several theoretical flaws inherent in the probalistic version are presented. Suggestions of possible directions for future research are offered. (Author)

The authors discuss changes that will appear in the 1988 edition of the General Educational Development (GED) test. Changes include (1) a focus on comprehensive, integrated skills; (2) a need for highly developed thinking skills; (3) use of a computer technology theme; (4) writing assessments; and (5) changes in content areas.

Although vocabulary tests have not been well suited to subdivisions that yield scores for different attributes, they have often been used in this manner. The question of whether such subscores can be justified from a measurement standpoint was studied. Items of a vocabulary test were classifed into three categories; the words were presented in…

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,…

Since all commonly used latent trait models assume a unidimensional test, the applicability of the procedure to obviously multidimensional tests is questionable. This paper presents the results of the application of latent trait, traditional, and factor analyses to a series of actual and hypothetical tests that vary in factoral complexity.…

A general process for testing the feasibility of applying alternative mathematical or statistical models to the solution of a practical problem is presented and flowcharted. The system is used to compare five models for test equating: (1) anchor test equating using classical test theory; (2) anchor test equating using the one-parameter logistic…

Field tests of test items are useful in developing cutting scores for important tests, such as teacher certification examinations and high school graduation tests, because they indicate test item quality and estimate future examinee performance. However, field test data may provide a faulty indication of examinee performance on the real test.…
