- Experimental Design
- Independent Groups
- Two separate groups of participants experience different conditions
- Evaluation
- Order effects aren't a problem
- Participants are less likely to guess aims
- Twice as many participants are needed
- Participant variables
- Random allocation used to prevent this
- Repeated Measures
- All participants experience all conditions
- Evaluation
- Order affects may arise
- Participants may figure out aims
- Demand Characteristic
- Participant variables are controlled
- Fewer participants are needed
- Matched Pairs
- Participants are paired on a variable e.g. IQ
- 1 from each pair would do a different condition
- Evaluation
- Order effects and Demand Characteristic less of problem
- Participants can't be matched exactly
- Matching may be time-consuming and expensive
- Participants are paired on a variable e.g. IQ
- Independent Groups
