Extensions of ANOVAs
This week we cover extensions of ANOVA models. The nice thing about this module is you literally know 95% of the material. The only thing you really have to learn this week is where the important buttons are. As you will see the extensions of ANOVA model captures what we’ve learned in multivariate regression. In fact, you could get the exact same answers if you ran a multivariate regression model. The reason why we explore these new models is because they are more appropriate for when our main explanatory variable is categorical nature, and when we also want to include control variables and/or interactions variables.
Module Learning Objectives
- Articulate when and why a researcher would use extensions of the ANOVA model.
- List the assumptions of the model
- Conduct the analysis in SPSS
- Interpret the outputs
- Identify the type of research questions appropriate for the model
