This paper describes a computer program which tests all pairwise comparisons of adjusted means in analysis of covariance by using Tukey-Kramer Test. The program contains: means of covariate, adjusted means of the criterion measure, sample size, mean square error, and the desired percentile point on the Studentized range distribution. (JAZ)

The Johnson-Neyman (JN) technique is a parametric alternative to analysis of covariance that permits nonparallel regression lines. This article presents computer programs for J-N using the transformational languages of SPSS-X and SAS. The programs are designed for two groups and one covariate. (Author/JAZ)

An algorithm and associated FORTRAN-77 computer subroutine are described for computing Goodman and Kruskal's tau-b statistic along with the associated nonasymptotic probability value under the null hypothesis tau=O. (Author)

A BASIC computer program is described which computes the Stuart-Maxwell test with its chi-square value and associate probability level. Following a significant chi-square test, the user has the option of performing multiple comparisons using McNemar's test for the significance of change. (Author)

This paper describes a set of four BASIC computer programs for computing the Rand index of cluster similarity. The routines calculate the unadjusted Rand Index; the separate routines are designed to handle problems of different sizes and alternate methods of data storage. (Author)

This paper describes two BASIC computer programs that calculate Hotelling's T-square either for one sample or for two samples. Output of the progams includes the Mahalanobis distance D-square, the F ratio associated with T-square, and its probability level. (Author)

A nonparametric Mokken scale analysis and program is described. Three procedures of scaling (a search procedure, evaluation of the whole set of items as a scale, and extension of an existing scale) provided a coefficient of scalability for all the items together that satisfy the criteria of the Mokken model. (Author/LMO)

A description of a Mokken test program to test the robustness of nonparametric Stochastic scales is presented. For each sample and the whole population, different scale statistics (both on scale and on item level) are computed recursively. A statistic T is presented for testing the robustness of the scales in the samples. (Author)

This paper summarizes much of the available information concerning the reliability and validity of the Tests of General Educational Development (GED Tests). The data suggest that the results are sufficiently reliable for continued use and that the validity evidence generally supports the intended uses of the tests. (Author/LMO)

A battery of nine cognitive abilities tests to assess verbal, spatial, perceptual speed, and memory abilities in children at age four was constructed and administered to a sample of 267 children in the Colorado Adoption Project. Exploratory and confirmatory factor analyses revealed four correlated factors that adequately describe the covariation…

Local norming data from the Brief Index of Adaptive Behavior are presented, as are construct and concurrent validity data. Participants in three studies were 430 children. Factor analytic results from Study 1 yielded an easily interpreted three-factor solution; conventional item analysis techniques yielded significant item-domain and item-total…

The predictive validity of the Standard Progressive Matrices (SPM) was examined with a sample of 212 sixth-grade students and 214 seventh-grade students. Correlation coefficients between the SPM and the California Achievement Tests of Reading, Language, and Mathematics ranged from .34 to .60. (Author/LMO)

Concurrent validity of the Scholastic Aptitude Test (SAT) and the Israeli Inter-University Psychometric Entrance Test (IUPRT) was supported by a high level of correlation, including a correlation of .85 between SAT and IUPET total scores. Transformation equations were presented to estimate performance on one test from the other. (Author/LMO)

This study investigated the effects of past computer experience on the computerized aptitude test performance of college students. Subjects were 92 undergraduates who completed an arithmetic reasoning test by computer and a Computer Experience Questionnaire. Past computer experience did account for a significant amount of variance on the…

This study investigated the construct and concurrent validity of a standardized academic self-concept measure--Dimensions of Self-Concept (DOSC) Form H--and a measure of locus of control involving learning-related activities--the Intellectual Achievement Responsibility Questionnaire (IAR). (LMO)
