The Mathematics Anxiety Rating Scale (MARS) (F. Richardson and R. Suinn, 1972) was submitted to a reliability generalization analysis to characterize the variability of measurement error in MARS scores across administrations and to identify possible study characteristics that are predictive of reliability variation. The meta-analysis was performed…

The literature on measurement reliability shows the consensus that group heterogeneity with regard to the trait being measured is a factor that affects the sample measurement reliability, but the degree of such effect is not entirely clear. Sample performance also has the potential to affect measurement reliability because of its effect on the…

This test-retest reliability study was conducted to test the reliability of an instrument designed to measure the relative importance of eight implementation conditions. Data for the Ensminger-Surry Implementation Profile Instrument (ESIP) were gathered starting January 2003. Participants were from a variety of occupations. Ages ranged from the…

A matrix of characteristics associated with transformational leadership and with high reliability organizations was developed. Using the matrix as a lens, researchers examined a successful school involved in a school improvement effort to understand the success more fully. Transformational leaders provide opportunities for personal growth for…

Where the accuracy of a measurement is important, whether for scientific or practical purposes, the investigator should evaluate how much random error affects the measurement. New research may not be necessary when a procedure has been studied enough to establish how much error it involves. But, with new measures, or measures being transferred…

This study attempts to determine the extent of agreement on the Torrance Tests of Creative Thinking scores among independent scorers with no training other than individual study of the scoring guides, and a scorer trained by Torrance. (Author)

The purpose of the current research has been to establish the factorial validity and reliability of the Work Components Study in the public school system. (Author/RK)

Study refers to J. A. Bowers' A note on Gaylord's Estimating test reliability from the item-test correlations,''' EJ 041 295. (CB)

For the purposes of this study, a test-retest method of determining reliability was utilized. Results indicated that the instrument appears to be reliable in assessing attitudes-beliefs toward smoking. (Author)

Examines the effects of four parameters on the accuracy of test equating under a relaxed definition of test form equivalence. The four parameters studied were sample size, test form length, test form reliability, and the correlation between true scores of the test forms to be equated. (CK)

The consequences of the assumption that the expected score is equal to the true score are shown and alternatives discussed. (MS)

Investigates the effects of four typewriter faces and handwriting on the level and reliability of grades awarded to English themes. (DG)
