Generalizability theory is a modern, powerful, and broad framework used to assess the reliability, or dependability, of measurements. While there exist classic works that explain the basic concepts and mathematical foundations of the method, there is currently a lack of resources addressing computational resources for those researchers wishing to…

Based on analyses of Maclean's ranking data pertaining to Canadian universities published over the last 24 years, we present a summary of statistical findings of annual ranking exercises, as well as discussion about their current status and the effects upon student welfare. Some illustrative tables are also presented. Using correlational and…

The first step in the Validity and Reliability Study summarizes the history and purpose of California's quality rating and improvement system (QRIS), reviews findings from other QRIS evaluation studies, and describes the approach to validating the system in California. The majority of this report focuses on providing context for the California…

Although a great deal of attention has been devoted over a period of years to the estimation of reliability from item statistics, there are still gaps in the mathematical derivation of the Kuder-Richardson results. The main purpose of this paper is to fill some of these gaps, using language consistent with modern probability theory. (Author)

This study in parametric test theory deals with the statistics of reliability estimation when scores on two parts of a test follow a binormal distribution with equal (case 1) or unequal (case 2) expectations. In each case biased maximum-likelihood estimators of reliability are obtained and converted into unbiased estimators. Sampling distributions…

Results of a comparative study of F and Q tests, in a randomized block design with one replication per cell, are presented. In addition to these two procedures, a multivariate test was also considered. The model and test statistics, data generation and parameter selection, results, summary and conclusions are presented. Ten tables contain the…

Describes development of the Kirton Adaption Innovation Inventory (KAI) for rating respondents on a continuum of adaptiveness-innovativeness, discusses tests of the validity and utility of the KAI model, and evaluates the KAI model's characteristics. For availability see EA 507 670. (Author/JG)

Extends the theoretical and practical implications of organizational climate research based upon the data from two studies, Sims and LaFollette (1975) and Litwin and Stringer (1968). (Author/RK)

The goal of this investigation was to derive a common battery of tests for both whites and negroes, and utilizing, if possible, uniform selection standards. (Author)

Reports preliminary findings of a study which used a modified Admissible Probability Measurement (APM) test scoring system in the design of computer based instructional management systems. The use of APM for curriculum analysis is discussed, as well as its value in enhancing individualized learning. (Author/LRW)

This paper is an extended series of appendices to the report "Exploring the T.R.Q.: An Assessment of the Effectiveness of the Teachers' Rating Questionnaire," Report Number 123. It should be most useful to those familiar with multiple regression analysis and factor analysis and wishing a more complex record of the statistical procedures…

The Emory Word Analysis Skill Inventory (EWASI) was developed to diagnose individual word analysis skill abnormalities exhibited by students enrolled in private tutoring in the Emory University (Georgia) Reading Center. In the EWASI, 13 subscales contain three broad categories--consonants, vowels, and word structure. The goal, however, is to…

Since middle schools vary in their degree of implementation of middle school practices, this research was designed to compare the job satisfaction of middle school teachers with the degree of implementation of these practices. Six teachers from each of Colorado's 50 schools with the name "middle school" were randomly selected to serve as…

A diagnostic test in English as a second language should be a series of miniature tests on specific problems. Subscores in each area should be considered rather than a total score. The results should be used to probe mastery in an area rather than provide the means for comparing one student against another. The statistical reliability of the…
