Data collected from surveys can result in hundreds of variables and thousands of respondents. This implies that time and energy must be devoted to (a) carefully entering the data into a database, (b) running preliminary analyses to identify any problems (e.g., missing data, potential outliers), (c) checking the reliability and validity of the…

Objective: The purpose of this study was to evaluate the relationship between health literacy, self-care agency, social support and health status among elderly Chinese nursing home residents in Xinjiang. Design: Participants were selected using a stratified cluster random sampling design. Setting: The study was conducted from September 2011 to…

The study builds on a newly modified Technology Acceptance Model (TAM) to substantiate the motivation and operation of teachers' utilization of online learning resources. A "Comprehensiveness" construct is proposed in the modified TAM to reflect the breadth and depth of rich online knowledge. This new construct serves as the mediator…

This study investigates the mediatory role of exercise self-regulation role in the relationship between personality traits and anger management among athletes. The statistical population of this study includes all athlete students of Shar-e Ghods College, among which 260 people were selected as sample using random sampling method. In addition, the…

The main aim of this study is to find out to what extent do narcissistic personality traits predict internet addiction and cyber bullying in vocational high school students. For this study five hundred and eight vocational high school students (331 male students--66,2%, 169 female students 33,8% and 8 unstated [x-bar] 16,24) from Anatolian side of…

In this study, the direct and indirect relations between school culture and the organisational commitment of primary school teachers were analyzed. The subjects of the research consisted of primary school teachers who worked at a district in Istanbul in the academic year 2007-2008. The sampling group was defined by the cluster sampling method. In…

The purpose of the present study is to examine the role of Invitational Education and intelligence beliefs in the academic performance of high school students. The research population comprised all male and female students studying at high schools in the academic year of 2009-2010 in Kashmar, a city in Iran. Selected through multi-stage random…

Multisample measured variable path analysis is used to test whether causal/structural relations among measured variables differ across populations. Several invariance testing approaches are available for assessing cross-group equality of such relations, but the associated test statistics may vary considerably across methods. This study is a…

The purpose of this study was to assess the mediating effect of self-efficacy on the relationship between identity styles and academic achievement. Four-hundred high school students (200 male, 200 female) who were selected through cluster random sampling, completed the Revised Identity Styles Inventory (ISI, 6G) and Morgan-Jink Student Efficacy…

This paper presents the finding of an investigation for determining course achievement utilizing the statistical technique of path analysis. (Author)

The purposes of this study are: (1) to demonstrate the superiority of simple ridge regression over ordinary least squares regression through theoretical argument and empirical example; (2) to modify ridge regression through use of the variance normalization criterion; and (3) to demonstrate the superiority of simple ridge regression based on the…

Since the development of causal path analysis by Wright, both the standardized and unstandardized procedures in path coefficient estimates have been advocated in the related literature, but the superiority of one technique over the other has not been demonstrated empirically or mathematically. In this study, the sampling properties of both…

The sampling variability and zeta-values of parameter estimates for misspecified structural equation models were examined. A Monte Carlo study was used. Results are discussed in terms of asymptotic theory and the implications for the practice of structural equation models. (SLD)

The present study was designed to identify the impact of drinking problems, impulsivity, and a history of childhood physical abuse on both male-to-female (MFIPV) and female-to-male intimate partner violence (FMIPV). The data were collected in 1995 from a representative national sample of couples living in the contiguous 48 states. Using a…

An empirical sampling approach was used to assess the accuracy of a Taylor approximation for the estimation of sampling errors. The sampling errors were in the statistics involved in estimating a path model based on medium-sized samples gathered using five sample designs commonly used in educational research. (TJH)
