objective: the aim of this study is to explore the confirmatory factor analysis results of the persian adaptation of abbreviated math anxiety scale (amas), proposed by hopko, mahadevan, bare & hunt. method: the validity and reliability assessments of the scale were performed on 298 college students chosen randomly from tabriz university in iran. the confirmatory factor analysis (cfa) was carrie...

in the modern world, organizations are considered as intelligent systems. increased organizational intelligence (oi) helps organizations to effectively analyze their data, store results, and use outcomes for making professional decisions. the purpose of this study was to measure oi in agriculture- jihad organization in guilan. a sample of 201 out of personnel was selected from in agriculture- j...

The purpose of this study is to explore the psychometric quality of a self-evaluation instrument based on Gardner’s theory of multiple intelligences (1991; 1993; 1995). Self-evaluated intelligence is closely related to a person’s selfconcept and can reflect both general and academic components of it. Our data includes Finnish students from five different universities (N=256). The questionnaire ...

a valid questionnaire is a precursor to a sound measurement process. this study examined the psychometric properties of the persian version of the revised competitive state anxiety inventory – 2 (csai-2r). a total of 131 female taekwondo athletes (mean age =12.37 ± 2.52) from damghan completed csai-2r at competition venues. confirmatory factor analysis was used to analyze the structure of csai-...

Artificial data with known covariance structure was used to directly test confounding hypothesis using Bayesian confirmatory factor analysis with small variance informative priors. The priors were derived from two extreme scenarios of no versus maximum confounding via exposure variables. Large (N=5000) and small (N=100) sample analyses were performed for both continuous and binary variable mode...

to compare different qtl mapping methods, a population with genotypic and phenotypic data was simulated. in bayesian approach, all information of markers can be used along with combination of distributions of snp markers. it is assumed that most of the markers (95%) have minor effects and a few numbers of markers (5%) exert major effects. the simulated population included a basic population of ...
