When what is wrong seems right: A Monte Carlo simulation investigating the robustness of coefficient omega to model misspecification
(2021-11-15)Coefficient omega is a model-based reliability estimate that is unrestricted by assumptions of a unidimensional essentially tau equivalent model. Rather, omega can be adapted to suit the underlying factor structure of a ... -
Effect Sizes for Equivalence Testing: Incorporating the Equivalence Interval
(2021-11-15)Equivalence testing (ET) is a framework to determine if an effect is small enough to be considered meaningless, wherein meaningless is expressed as an equivalence interval (EI). Although traditional effect sizes (ESs) are ... -
Contextualizing Statistical Suppression Within Pretest-Posttest Designs
(2019-11-22)Statistical suppression occurs when adjusting for a variable enhances or substantially modifies the association between a predictor and an outcome. Although many methodologists have discussed this phenomenon, very little ... -
A Multi-Faceted Mess: A Review of Statistical Power Analysis in Psychology Journal Articles
(2019-11-22)The over-reliance on null hypothesis significance testing and its accompanying tools has recently been challenged. An example of such a tool is statistical power analysis, which is used to determine how many participants ... -
Best Practices for Constructing Confidence Intervals for the General Linear Model Under Non-Normality
(2018-05-28)Given the current climate surrounding the replication crisis facing scientific research, a subsequent call for methodological reform has been issued which explicates the need for a shift from null hypothesis significance ... -
Everything on the Table: Tabular, Graphic, and Interactive Approaches for Interpreting and Presenting Monte Carlo Simulation Data
(2018-05-28)Abstract Monte Carlo simulation studies (MCSS) form a cornerstone for quantitative methods research. They are frequently used to evaluate and compare the properties of statistical methods and inform both future research ... -
Evaluating Equivalence Testing Methods for Measurement Invariance
(2018-03-01)Establishing measurement invariance (MI) is important to validly make group comparisons on psychological constructs of interest. MI involves a multi-stage process of determining whether the factor structure and model ... -
A More Powerful Familywise Error Control Procedure for Evaluating Mean Equivalence
(2018-03-01)When one wishes to show that there are no meaningful differences between two or more groups, equivalence tests should be used, as a nonsignificant test of mean difference does not provide evidence regarding the equivalence ... -
A Differential Response Functioning Framework for Understanding Item, Bundle, and Test Bias
(2017-07-27)This dissertation extends the parametric sampling method and area-based statistics for differential test functioning (DTF) proposed by Chalmers, Counsell, and Flora (2016). Measures for differential item and bundle functioning ... -
Evidence-Based Recommendations of Reporting Results from Mediation Analysis: A Focus on Ease of Interpretation and Maximum Accuracy
(2016-11-25)Theoretical models of mediation are common in psychological research, but there is much variability in how results of mediation analyses are reported which could result in interpretational errors, misconceptions, and ... -
Effect Sizes for Single Case Experimental Designs and Their Utility for a Meta-Analysis: A Simulation Study
(2016-09-20)There has been a lack of consensus as to the optimal effect size for use in meta-analyses involving Single Case Experimental Designs (SCEDs). SCEDs are a set of experimental designs which produce data akin to short interrupted ... -
Equivalence Tests For Repeated Measures
(2015-12-16)Equivalence tests from the null hypothesis significance testing framework are appropriate alternatives to difference tests for demonstrating lack of difference. For determining equivalence among more than two repeated ... -
The Effects of Differential Between-Groups Skewness on Heteroscedastic, Trimmed Means, and Rank-Based Between Groups Procedures
(2015-08-28)Abstract The effect of differential between-group skewness was investigated for the traditional t- and ANOVA F tests, the Welch procedure without trimming (Welch, 1938) and with trimming and Winsorized variances (Yuen, ...
