Statistical Methods Seminar Description
Overview: Great! You have an idea you’re interested in, now what? You may even have a theory that X will predict Y, but the more important question, the question that we really what to know is, why does X predict Y, or when does X predict Y. Modeling these mechanisms of change are where Mediation and/or Moderation become your methodological hero!
Our Mediation and Moderation seminar will teach you the fundamentals of framing the relationships between your observations, including how to:
- Estimate, test, and interpret mediated (i.e., indirect) and moderated (i.e., interaction) effects using OLS regression.
- Combine mediation and moderation models to test conditional indirect effects.
- Use a macro called PROCESS for SPSS and SAS to test these models.
- Apply the latest methods in moderation and mediation analysis using R software.
Instructor: Mwarumba Mwavita Ph.D.
Mwarumba Mwavita is the Director of the Center for Educational Research and Evaluation (CERE) at Oklahoma State University. In addition, he is an Assistant Professor in the Research, Evaluation, Measurement and Statistics (REMS) program in the School of Educational Studies (SES). He received his Bachelor’s Degree in Physics and Education at Kenyatta University, Master’s at University of Central Oklahoma, and Ph.D. in Research, Evaluation, Measurement, and Statistics from Oklahoma State University in 2005. He teaches general linear model (ANOVA, Regression, Multivariate), Mixed Models, and Program Evaluation seminars.
Software and Computer Support
Participants need to bring a laptop computer with Wi-Fi capabilities.
All statistical software used at Stats Camp will be available, free to participants, on our SMORS (statistical modeling on remote servers) system for the duration of camp.
Instruction will be provided for the methods using the most current version of the PROCESS macro (processmacro.org). PROCESS is freely available as a macro for SPSS and SAS. SPSS and SAS are available for Windows, Mac, and Linux environments.
We shall use SPSS software for this seminar.
This seminar will be helpful for researchers in any field—including psychology, sociology, education, business, human development, political science, public health, communication—and others who want to learn how to apply the latest methods in moderation and mediation analysis using freely-available R software. Participants should have a good working knowledge of the principles and practice of multiple regression and elementary statistical inference.
- Intermediate proficiency in multiple linear regression
- Intermediate proficiency with at least once statistical software package (knowledge of SPSS or SAS are preferred, but not required).
- At least limited experience using syntax with statistical software.
Not required but advantageous:
- At least limited experience (e.g., graduate-level seminar) with multivariate data analysis.
- At least limited experience (e.g., graduate-level seminar) with investigating interactions (in r multiple linear regression or ANOVA)
No level of proficiency beyond basic awareness is assumed for skills related to:
- Mediation and moderation
- Advanced statistical techniques such as SEM, MLM, or logistic regression.
- Advanced mathematical or statistical topics such as matrix algebra or likelihood theory.
