Nonparametric Tests Of Interaction For The Two-Way Design With Skewed Distributions, Michael Ethan Hornsby Brown
Nonparametric Tests Of Interaction For The Two-Way Design With Skewed Distributions, Michael Ethan Hornsby Brown
Theses and Dissertations
The most common parametric procedure used to test main and interaction effects in the two- or more-groups factorial design is the analysis of variance (ANOVA) F test. Researchers in the behavioral and social sciences fields require statistical methods that are robust in the presence of deviations from the common parametric ANOVA assumptions of (a) normality, (b) homogeneity of variances among groups, and (c) independence of observations. When there is concern that the parametric assumptions are violated, nonparametric procedures can be employed that do not make as many initial assumptions about the parent populations. Of particular interest in the two-factor design …
Examining Recommended Strategies For Accommodating Negatively Worded Items, Jungsun Go
Examining Recommended Strategies For Accommodating Negatively Worded Items, Jungsun Go
Theses and Dissertations
The purpose of this study was to investigate the effectiveness of four different models (bifactor, CTC(M-1), CTCU and unidimensional) as to optimal model selection when the wording effect associated with negatively worded items was present. A Monte Carlo simulation study was conducted to compare model-data fit and accuracy in parameter estimates of the four models. Design factors include: two true models (CTC(M-1), CTCU models) × three sample sizes (small N=250, moderate N=500, large N=1,000) × two item ratios (positive items:negative items = 2:1 or 1:1) × three distributions (distribution of negative items; symmetric, moderately asymmetric, and extremely asymmetric). The generated …
The Hero Within: Developing The Psychological Capital Of First-Generation Students, Mary Elizabeth Sewell
The Hero Within: Developing The Psychological Capital Of First-Generation Students, Mary Elizabeth Sewell
Theses and Dissertations
Psychological capital (PsyCap) is a higher-order construct comprised of four psychological resources: hope, efficacy, resilience, and optimism (HERO), and has been linked to academic achievement and engagement (Hazan Liran & Miller, 2019; Luthans, et al., 2012). Interventions designed to build PsyCap may be particularly helpful for firstgeneration (FG) students who face additional challenges in higher education. This study aimed to: (1) explore differences in PsyCap among FG and continuing generation (CG) students; (2) investigate relationships between PsyCap, GPA, and persistence; and (3) examine the impact of a 2-hour PsyCap micro-intervention (PCI) on FG students’ academic PsyCap, academic achievement (GPA), and …
Identifying Attributions And Predictors Of High School Dropout In Rural Youth: A Mixed Methods Approach, Karla Swayngim Reed
Identifying Attributions And Predictors Of High School Dropout In Rural Youth: A Mixed Methods Approach, Karla Swayngim Reed
Theses and Dissertations
Graduating high school is an important educational milestone that is related to better life outcomes; however, high school dropout remains an issue in the United States (US). This mixed methods study began with a qualitative stage using attribution theory to identify the factors rural youth perceive as responsible for their decision to drop out of high school. Focus groups were conducted with youth from a rural area in South Carolina (SC). Seven themes were identified across the two categories of Internal and External Focus. Internal Focus themes included: (a) ability/self-efficacy, (b) effort, (c) plans for the future, and (d) other …
An Examination Of Measurement Invariance With A Multi-Group Confirmatory Factor Analysis Approach, Ruiqin Gao
An Examination Of Measurement Invariance With A Multi-Group Confirmatory Factor Analysis Approach, Ruiqin Gao
Theses and Dissertations
This multiple-manuscript dissertation explored the measurement invariance (MI) testing with multiple-group confirmatory factor analysis (MG-CFA) approach from different perspectives. Study 1 explored MI from a theoretical perspective by conducting a systematic review study on MI practices in education. The findings of this study indicated inconsistency in MI practices and showcased the limitations of the MI practices conducted by researchers in the field of education. Study 2 examined MI from an empirical perspective by implementing a cultural MI test of Strengths and Difficulties Questionnaires for elementary school students in the United States and China. The study provided a step-by-step demonstration of …
