Data collected from surveys can result in hundreds of variables and thousands of respondents. This implies that time and energy must be devoted to (a) carefully entering the data into a database, (b) running preliminary analyses to identify any problems (e.g., missing data, potential outliers), (c) checking the reliability and validity of the…

Testing in educational system perform a number of functions, the results from a test can be used to make a number of decisions in education. It is therefore well accepted in the education literature that, testing is an important element of education. To effectively utilize the tests in educational policies and quality assurance its validity and…

Study determines that solutions derived by multiple group analysis and item-total correlation analysis were generally most interpretable from a psychological perspective. It was concluded that their application to test construction is preferred over Procrustean or confirmatory maximum likelihood approaches. (RB)

A set of 150 experimental personality items was constructed for an alternate form of the word association personality worksample developed by the Johnson O'Connor Research Foundation. The items were intended to possess several semantic properties hypothesized to facilitate discrimination between objective and subjective examinees. Specifically,…

Equations are derived to enable the graphic approximation of the item parameters of the stochastic mental test models, i.e., the generalized normal ogive and logistic models. The item parameters for the models are discriminatory power, difficulty, and probability of chance success. Suggested uses for the approximations were to provide a basis for…

A computer-administered version of the Yale-Brown Obsessive-Compulsive Scale was administered to 31 patients with obsessive-compulsive disorder, 16 with other anxiety disorders, and 23 nonpatient controls. The computer version correlated highly with the clinician-administered version and was well understood and liked by subjects. (SLD)

This collection of papers, concerned with the nature and theory of intelligence, forms part of a project to integrate test and factor theory with the empirical, functional relationships involving standard intelligence tests. The project will render more objective the use of factor analysis in personnel research. A definition of intelligence…
