This study analyzed the results of applying two different methods of likert-scale construction (single-column and discrepancy-column formats). The findings indicated that the discrepancy format provides stronger discrimination for purposes of measuring need. (Author/BW)

It was predicted that there would be variable IQ discrepancies at different ages because of differential age adjustments on the norms of the Wechsler Adult Intelligence Scale (WAIS) and the WAIS-Revised (WAIS-R). The use of equivalent WAIS and WAIS-R sums of scaled scores demonstrated the predicted variable discrepancies. (Author/BW)

The purpose of this study was to determine the reliability of the Spanish translation of the Coopersmith Self-Esteem Inventory with a group of Puerto Rican students on the island and another on the mainlands. It was found to be reliable for both groups. (Author/BW)

The presently viewed role and utility of measures of instructional sensitivity are summarized. A case is made that the rationale for the assessment of instructional sensitivity can be applied to all achievement tests and should not be restricted to criterion-referenced mastery tests. (Author/BW)

The effects of some restraints not included in the classical assumptions of the F- and H-Test (e.g., correlation of mean and sample size) were examined in a simulation design. Also simulated was a situation in which two assumptions were not met simultaneously. (Author/BW)

A supplementary treatment is proposed which helps identify sources of bias affecting groups of test items. This treatment is illustrated with the tranformed item-difficulty method as applied to an evaluation of a test used to help select applicants to be admitted to an aviation training program.

After a review of the disadvantages of linear models for estimating the probability of academic success from previous school records and admission test results, the use of a probit model is proposed. The model is illustrated with admissions data from the Ecole des Hautes Etudes Commerciales in Montreal. (Author/BW)

The present study compares the robustness of two different one way fixed-effects analysis of covariance (ANCOVA) models to investigate whether the model which uses a test statistic incorporating estimates of separate unequal regression slopes is more robust than the conventional model which assumes the slopes are equal. (Author/BW)

A computer program is described which provides comprehensive information on test profile differences among independent groups based upon profile centroid separation, shape, elevation, and scatter. Descriptive statistics, univariate and multivariate measures of strength of association, test of homogeneity of covariance matrices, and comparative…

This program computes multiple judge reliability levels under the following conditions. (1) different sets of judges perform the ratings; (2) the number of judges is a constant; and (3) the scale of measurement is nominal. (Author)

When selection occurs on the basis of two or more predictors, multivariate restriction of range can reduce various parameters of a validation study. A Statistical Analysis System (SAS) and a Fortran IV program are described that allow for correction of criterion standard deviation(s) and zero-order validities. (Author)

This paper describes a microcomputer program that extracts principal components from a correlation matrix and rotates them to a varimax solution. Eigenvalues, variances associated with each component, unrotated component loadings, and varimax rotated loadings are output by the program. (Author)

Intended for use on Conversational Monitor System (CMS), the Tukey FORTRAN program facilitates pairwise comparisons among means following a significant Fratio in an analysis of variance. Tukey's statistic can be obtained by entering information regarding the design and analysis of variance results. Two variations are also available. (Author/BS)

Two studies examined the effect of making the correct answer of a multiple choice test item grammatically consistent with the item. American College Testing Assessment experimental items were constructed to investigate grammatical compliance to investigate grammatical compliance for plural-singular and vowel-consonant agreement. Results suggest…

The Figural, Symbolic, and Semantic dimensions or the Structure of Intellect Learning Abilities (SOI-LA) tests have been employed as prescriptive tools for matching students to appropriate methods of reading instruction. A multiple-group factor analysis revealed strong evidence of their construct validity in a normative sample of 364 second…
