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…

In this research, it is aimed to develop a valid and reliable test to determine the drawing a shape-schema and making a table levels of prospective teachers at Mathematics and Science Education, Turkish and Social Sciences Education and Basic Education Departments. In this process, a comprehensive item pool has been prepared with the table of…

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…

This manual provides guidance and documentation for users of the longitudinal kindergarten-fourth grade (K-4) data file of the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011). It mainly provides information specific to the fourth-grade round of data collection. The first chapter provides an overview of the…

It has been the impression of the authors that a significant minority of MMPI profiles produced by adolescents suggest schizophrenia when such a process is not evident clinically. The present study was conducted in order to measure and better understand the frequency of false positive adolescent MMPI profiles. (Author)

This study investigated (a) interscorer reliability of the Bender-Gestalt Test by using more than one person to score the same test protocols; and (b) rate-rerate reliability of the Bender-Gestalt Test after a half-year interval. (Author)

A study examined reliability and validity of the Test of Playfulness (ToP) with 25 children who have physical disabilities but no cognitive limitations, comparing their scores with those of able-bodied peers and examining patterns of difference in test items between groups. The mean ToP scores of the two groups did not differ. (Contains 33…

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)

Purpose of this study was to determine if children in the first grade could discriminate whether two paired chords were the same or different, could learn to associate a tone with a chord in four brief training sessions, and could improve more in harmonic discrimination when performing chords in the training sessions than when merely listening to…

Eight asymptotically robust tests of population correlation coefficient equality are proposed and are studied along with two parametric tests. Monte Carlo simulation is used to compare the small sample performance of these ten procedures. The sampled distributions consist of the normal distribution, two mixed normal distributions and four…

Current methods of obtaining reliability coefficients for mastery tests are laborious from a practitioner's perspective. Some methods require two test administrations; while others require access to computer facilities and/or advanced measurement and statistical procedures. This report provides tables from which practitioners can read such…

The purpose of this study was to reexamine the earlier results for two item-writing practices using different methods for developing the instruments. (Author)
