Flashcards in Factorial independent ANOVA Deck (8)
What sort of IV should be used in two-way ANOVAs?
Must be categorical (e.g. gender, religion, etc)
What does a factorial ANOVA examine?
-Main effects (the effect on its own)
-Interactions (whether factors interact, if the effect of one factor is dependent on another)
What are the advantages of factorial ANOVAs compared to one-way?
1. The ability to analyse interactions (e.g. drug A and B may not work independently, but do together)
2. More powerful (adding factors reduce error by accounting for variance that would e unexplained)
What test would you use if Levene's test is significant?
What test would you used if there are slight differences in number of participants in each group?
What test would you used if there are very different numbers of participants in each group?
