Classic parametric statistical significance tests, such as analysis of variance and least squares regression, are widely used by researchers in many disciplines, including psychology. For classic parametric tests to produce accurate results, the assumptions underlying them (e.g., normality and homoscedasticity) must be satisfied. These assumptions…

The "Special Ability Selection Examination" (SASE), which is used to select appropriate students for the music education departments of educational faculties in Turkey, has many subsections and must evaluate highly competitive cohorts of students according to a broad range of criteria. The test consists of three subsections, with a large…

Objective: To assess reproducibility of a School-Based Nutrition Monitoring (SBNM) questionnaire for fourth-grade students. Design: Test-retest. Setting: Fourth-grade elementary school classrooms. Participants: Multiethnic fourth-grade students from 2 area school districts (N = 322). Main Outcome Measures: Reproducibility coefficients with time…

Background: In the UK clinical supervision is regarded as an essential process supporting quality improvement within the clinical governance framework, and the Royal College of Speech and Language Therapists regards it as a tool for promoting critical reflective practice. There is limited evidence of the impact on practice or improvements in…

This book contains a compilation of papers presented at the International Psychological Applications Conference and Trends (InPACT) 2019, organized by the World Institute for Advanced Research and Science (W.I.A.R.S.). Modern psychology offers a large range of scientific fields where it can be applied. The goal of understanding individuals and…

The purpose of this study is to determine (1) whether the previously observed vulnerability of WISC subtests to tester effects appeared under ordinary testing conditions, and (2) which subtests were most susceptible to these effects. Results support the presence of both general and differential vulnerability of subtests. (Author)

For classical, norm-referenced test reliability, Cronbach's alpha has been shown to be equal to the mean of all possible split-half Pearson product-moment correlation coefficients, adjusted by the Spearman-Brown prophecy formula. For criterion-referenced test reliability, in an analogous vein, this paper provides the rationale behind, the analysis…

Three successively simpler formulas for approximating the standard error of measurement were derived by applying successively more simplifying assumptions to the standard formula based on the standard deviation and the Kuder-Richardson formula 20 estimate of reliability. The accuracy of each of these three formulas, with respect to the standard…

Two designs for comparing a judge's ratings with a known standard are compared: (1) Subjects are categorized into classes, with no knowledge of the size of either group; and (2) the judge is told the actual number allowed in each class. The probability distribution of the total number of correct choices is developed for each case, and their power…

A comparison of three multivariate models (canonical reliability model, maximum generalizability model, canonical correlation model) for estimating test battery reliability indicated that the maximum generalizability model showed the least degree of bias, smallest errors in estimation, and the greatest relative efficiency across all experimental…

Current methods for obtaining reliability indices for mastery tests can be laborious. This paper offers practitioners tables from which agreement and kappa coefficients can be read directly and provides criterion for acceptable values of agreement and kappa coefficients. (TJH)

States that taking a high school psychology course did not improve the performance of college students in an introductory psychology class on a modified version of Vaughan's misconceptions test (Test of Common Beliefs). Concludes that while college experience did lead to some improvement, comparison with other studies indicates that perhaps the…
