14. factorial designs
Cards in this deck (7)
- 1what is a factorial design?an experiment that has two or more independent variables
- 23 types of factorial design + explanation1. independent factorial design (2+ IV's, each with different entities)
2. repeated-measures (related) factorial design (2+ IV's, same entities in all conditions)
3. mixed (factorial design) (2+ IV's, some with different entities, some with the same entities) - 3what do you call a design that has two or more categorical predictor variables?a factorial ANOVA
- 4what are the subdivisions of the SS model in a factorial design?- variance explained by the first predictor (SSa)
- variance explained by the second predictor (SSb)
- variance explained by the interaction of a and b (SSaxb) - 5f-statistics and Type I errorsthe F statistics are not independent, so they don't control the Type I error rate
- 6can you code contrasts for two or more IV's?no, you can only select one
- 7how to interpret interaction graphsnon-parallel lines indicate some degree of interaction, depending on how non-parallel they are. if they cross, that hints at a possible significant interaction.
