Robustness And Power Comparison Of The Mood-Westenberg And Siegel-Tukey Tests, Linda Candy Lowenstein

Wayne State University Dissertations

The author examined how, in the context of experimental design, one might become aware of the Behrens-Fisher problem (heteroscedasticity) in order to apply an approximate solution, such as the Yuen's statistic (1974). It was expected that both the Mood-Westenberg dispersion test (1948) and the Siegel-Tukey test (1960) would remain robust with respect to Type I and Type II error properties (and associated power levels) for detecting variance changes when their assumptions of equal means was slightly violated (i.e., the Behrens-Fisher problem). With the use of Monte Carlo Simulations, the author reviewed 34,606 permutations composed of interactions between various sample sizes, …

The Impact Of Academic Optimism On Student Achievement In Five Middle Schools, Rita Hickey Teague

Wayne State University Dissertations

This study addressed the research question: To what extent do the measures of academic optimism predict academic achievement? The study was conducted in two suburban, adjacent school districts with 102 middle school teachers from five middle schools participating.

A non-experimental, multiple regression research design was used as no treatment or intervention was provided. Data collection tools were a revision of three surveys that purport to measure the three components of academic optimism, and school level outcomes from the Michigan Education Assessment Program and the Measures of Academic Progress. Using Google Forms, data were collected electronically at faculty meetings with submission …

An Evaluation Of Wayne State University's Educational Evaluation And Research Program, Willie L. White Ii

Wayne State University Dissertations

This is a mixed-methods evaluation of the Educational Evaluation and Research program at Wayne State University. The process of evaluation involved determining the efficacy of triangulating qualitative and quantitative methods of evaluation in order to access the EER program's goal acquisition. The process of evaluation commenced with a qualitative method of interviewing faculty members and was triangulated quantitatively with a likert scale survey that was modified from Wayne State University's Student Evaluation of Teaching Survey (SETS). The Student Evaluation of the Educational Evaluation and Research Program (SEEERP) was designed to measure graduate students' perspectives of EER goals and objectives acquisition. …
