The Dependent Samples T And Wilcoxon Sign Rank Maximum Test, Saverpierre Maggio
The Dependent Samples T And Wilcoxon Sign Rank Maximum Test, Saverpierre Maggio
Wayne State University Dissertations
A maximum test using the parametric dependent samples t-test and the non-parametric Wilcoxon sign rank test was created using a FORTRAN program and various subroutines of the International Mathematical and Statistical Libraries (IMSL, 1980). Two tailed critical values were derived from a mixed normal distribution. Critical values obtained were at the 0.05, 0.025, 0.01 and 0.005 alpha levels via sample sizes (n) 8 through 30, 45, 60, 90 and 120. Critical values were compared to values obtained through the application of the Bonferroni correction method. It was concluded that the Bonferroni is an unnecessary method. Findings of the study are …
Bully/Victim Power Inventory: Measuring The Power Imbalance In The Bully/Victim Relationship, Marybeth Plonkey-Lehto
Bully/Victim Power Inventory: Measuring The Power Imbalance In The Bully/Victim Relationship, Marybeth Plonkey-Lehto
Electronic Theses and Dissertations
The empirical study of the power imbalance in the bully/victim relationship has impeded research synthesis, and the need for a quantitative measure of this key component has been well established in the literature. Lack of differentiation between victimization with and without power imbalance has been cited as a possible cause for imprecise measurement. Increased precision in bully victimization measurement is needed to accurately inform research investigating psychosocial health, treatment and positive outcomes, in addition to prevention and intervention programs. Therefore, the purpose of this dissertation was the initial development and validation of the Bully/Victim Power Inventory aimed at differentiating perceived …
A Study Of Birth Weight As A Predictor Of Cognitive Ability In Childhood : Applications Of Loess Regression And Generalized Propensity Score Methods, Xiaoyuan Tan
Legacy Theses & Dissertations (2009 - 2024)
This study applied nonparametric loess regression to describe the predictive association between birth weight and cognitive ability in childhood and generalized propensity score methods to control the confounding of multiple covariates that summarize prenatal differences.
