To examine the reproducibility of three measurement techniques used to determine creatine kinase, interleukin-6 and high-sensitivity C-reactive protein, 50 participants had blood samples taken on two occasions. Fingertip plasma samples were analysed using the Reflotron for CK determination. Venous blood samples collected into serum separator tubes…

The purpose of this article was two-fold (1) provide an overview of the commonly reported and under-reported absolute agreement indices in the kinesiology literature for continuous data; and (2) present examples of these indices for hypothetical data along with recommendations for future use. It is recommended that three types of information be…

Educators use various statistical techniques to explain relationships between latent and observable variables. One way to model these relationships is to use Bayesian networks as a scoring model. However, adjusting the conditional probability tables (CPT-parameters) to fit a set of observations is still a challenge when using Bayesian networks. A…

This article explores ways to assess interactional performance, and reports on the use of a test format that standardizes the interlocutor's linguistic and interactional contributions to the exchange. It describes the construction and administration of six scripted speech tasks (instruction, advice, and sales tasks) with pre-vocational learners (n…

The aim of this study is to develop a scoring rubric to assess primary school students' problem posing skills. The rubric including five dimensions namely solvability, reasonability, mathematical structure, context and language was used. The raters scored the students' problem posing skills both with and without the scoring rubric to test the…

This thematic-based meta-analytic study aims to examine the effect of creativity on the academic success and learning retention scores of students. In the context of this aim, 18 out of 225 studies regarding creativity that were carried out between 2001 and 2011 have been obtained from certain national and international databases. The studies…

Ensuring internal validity in quantitative research requires, among other conditions, reliable instrumentation. Unfortunately, however, second language (L2) researchers often fail to report and even more often fail to interpret reliability estimates beyond generic benchmarks for acceptability. As a means to guide interpretations of such estimates,…

The study compared the agreement, internal consistency, and measurement stability of the GE iDXA, BOD POD, and InBody 720. Body composition of 43 men and 37 women (31.4 ± 10.7 years; 90% Caucasian and 10% other) was assessed in triplicate using each method over two different days. Mean percent body fat (% BF) of the participants was different for…

The 0.70 and 0.80 reliability standards, proposed by Jum Nunnally, are widely employed across a spectrum of research domains. Nonetheless, due to their arbitrary nature, both standards fail to satisfy the needs of researchers. This paper presents a set of formulas that can be used to compute minimum reliability standards as a function of a…

In urban schools, along with skills for effective teaching, successful teachers must also possess values and belief systems conducive to teaching effectively in diverse settings (Becker, Kennedy, & Hundersmarck, 2003; Haberman, 2008; Metzgar & Wu, 2008). As demonstrated in CAEP standard 3, there is a critical need for EPPs to admit…

Data derived from universal screening procedures are increasingly utilized by schools to identify and provide additional support to students at risk for behavioral and emotional concerns. As screening has the potential to be resource intensive, effort has been placed on the development of efficient screening procedures, including brief behavior…

This study aimed to compare between the students' self-assessment and teachers' assessment. The study sample consisted of 71 students at Tafila Technical University studying Introduction to Psychology course. The researcher used 2 students' self-assessment tools and 2 tests. The results indicated that students can assess themselves accurately if…

Much of the science reported in the media depends on correlation coefficients. But the size of correlation coefficients depends, in part, on the reliability with which the correlated variables are measured. Understanding this is a statistical literacy issue.

Heightened accountability pressures and an increased emphasis on teaching quality have directed scholarly attention to scrutinizing instruction, particularly with respect to issues of validity and reliability. However, these attempts have largely been directed toward "core" content areas and investigated generic or content-specific…

Introduction: Given that people rely heavily on their party affiliation to make their political decisions, an interesting dilemma occurs when people are exposed to counter-attitudinal information from the party they identify with. This paper examines how exposure to counter-attitudinal messages from the party an individual identifies with…
