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 …
An Examination Of Attachment And Aspirations In Diverse Rural Youth: The Role Of Peers And Teachers, Gresi Bonomo Irdam
An Examination Of Attachment And Aspirations In Diverse Rural Youth: The Role Of Peers And Teachers, Gresi Bonomo Irdam
Theses and Dissertations
This dissertation consists of three studies that examined diverse rural youths’ educational and rural aspirations. These studies have the potential to inform rural communities, educators, and parents by providing novel understandings of how peers and teachers in mathematics and science classrooms influence diverse rural youths’ rural attachment, and aspirations (i.e., educational, rural residential, community, and proximity). Thus, the purpose of this dissertation was to investigate rural teachers and their diverse students from White, African American, Hispanic, and Native American backgrounds. In particular, the studies within this dissertation examine how teachers’ social connectedness to their rural communities relates to their teacher …
High School Students’ Math And Science Motivation Profiles: Stability And Relationship With Their Stem Career Aspirations, Jiali Zheng
Theses and Dissertations
Motivation to study mathematics and science is an important influencing factor of career aspirations in STEM fields which predicts STEM major choice in college and STEM careers after graduation. Using restricted data from a nationally representative sample HSLS:09, the current study identified U.S. high school students’ motivation profiles in mathematics and science courses in 9th and 11th grade, examined the stability of these profiles across the two time points, and studied the association between 11th grade motivation profiles and STEM career aspirations. Differences between male and female students in motivation profiles, profile stability and career aspirations were …
