Study Notes
Factorial Designs and ANOVA
- Factorial designs include two or more independent variables and measure their impact on the dependent variable as well as the interaction between them.
- This design allows for testing multiple hypotheses in one study, including main effects and interaction effects.
- Graphical representation of factorial designs can show interaction effects, where the lines cross each other.
- ANOVA can analyze any factorial design, where the number of effects analyzed depends on the number of independent variables.
- A mixed factorial design can have independent variables that are within subjects, between subjects, or a combination of both.
- ANCOVA (analysis of covariance) allows for removing the variance due to confounding variables from the analysis.
- MANOVA (multivariate analysis of variance) tests more than one dependent variable at the same time.
- The numbers in a "2x3 design" refer to the number of independent variables and levels for each variable.
- ANOVA is a flexible data analysis approach that can handle any number of independent variables and any combination of within and between subjects factors.
- ANCOVA and MANOVA are variations of ANOVA that allow for removing confounding variables and analyzing multiple dependent variables, respectively.
- Chapter 12 is short and sweet, and the next steps could be completing the worksheet and finding ways to decompress.
- Understanding factorial designs and ANOVA can help in designing and analyzing research studies with multiple independent or dependent variables.
