Teaching is a stressful profession with a high turnover rate. Schools and related institutions need to take more action to support teachers and keep teacher stress at a manageable level. The continued research and practical effort require measures to examine teachers' stress in a briefer and accurate manner. The Teacher Stress Scale is a recently…

The purpose of this study was to use multidimensional scaling (MDS) to investigate relations among scores from the standardization sample of the Wechsler Intelligence Scale for Children--Fifth edition (WISC-V; Wechsler, 2014). Nonmetric two-dimensional MDS maps were selected for interpretation. The most cognitively complex subtests and indexes…

We used data simulations to test whether composites consisting of cohesive subtest scores are more accurate than composites consisting of divergent subtest scores. We demonstrate that when multivariate normality holds, divergent and cohesive scores are equally accurate. Furthermore, excluding divergent scores results in biased estimates of…

A common problem in practical educational research is that of perfect scores which result when latent trait models are used. A simple procedure for managing the perfect and zero response problem encountered in converting test scores into measures is presented. It allows the test user to chose among two or three reasonable finite representations of…

During early attempts to interpret factors represented in scores on the Gumpgookies test, an instrument designed to tap motivation to achieve in young children, the factors identified by ordinary factor-analytic techniques were found to be confounded by the subjects' response sets. This paper proposes a method for defining objectively irrelevant…

The stability and change of verbal, non-verbal, and total IQ scores from group tests were investigated for students tested at Grades 1, 2, 4, 7, 9, and 11. Conclusions are discussed in detail, and the following recommendations are made: (1) Group intelligence tests should not be routinely administered in Grades 1 and 2 unless the users and…
