Chapter 10: Complex Experimental Designs Flashcards
What are factorial designs?
Designs with more than 1 IV (factor)
2x3
How many IVs, conditions, potential main effects, and potential interactions are there?
IV- 2
Conditions- 6
Main effects- 2
Interactions- 1
2x2x2
How many IVs, conditions, potential main effects, and potential interactions are there?
IVs- 3
Conditions- 8
Main effects- 3
Interactions- 4
3 factors always equals how many potential interactions?
4
What 2 kinds of info do factorial designs produce?
Main effects- The effect of each IV by itself
Interaction effects- the interaction between the IVs
What are the three types of assignment procedures?
- Independent group design(between subjects)- different groups assigned to conditions
- Repeated measures design(within-subjects)- same participants in all conditions
- Mixed factorial design- one IV has same participants, another doesn’t
What assignment procedure/design is shown?
Independent group design
What type of assignment procedure/design is shown?
Repeated Measures design
What type of assignment procedure/design is shown?
Mixed design
Answer the questions in the image shown
- Design- 3x3
- IVs- 2
- Conditions- 9
- Main effects- 2
- Interactions- 1
What are complex designs?
A design that has more than 2 conditions
When would you use complex/factorial designs?
When you suspect a curvilinear relationship, as you can only see this if you have 3+ conditions
If the marginal means on a factorial design are the same, is there a main effect?
No, there isn’t
If the marginal means on a factorial design aren’t the same, is there a main effect?
Yes, there is
