Content of the notes (3)
Page 1
Repeated Measures Design
1 group
Each participant subject to every condition
Advantages
Cheap
Quick
No participant variation
Disadvantages
Order effects
Purpose of experiment may be revealed
Boredom effect
Page 2
Independent Groups Design
2 (+) groups that complete different tasks
e.g. Group 1 completes task with music, Group 2 without music
Advantages
No order effects
No boredom effect
Participants unlikely to discover experiment purpose
Disadvantages
Open to participant variation (e.g. ability)
Costly due to more participants
Open to experimenter bias if group allocation isn't random
Page 3
Matched Pairs Design
2 (+) Groups
Participants are matched into each condition as closely as possible based on important factors (e.g. age, gender)
Advantages
No order effects
Reduced participant variation
Participants unlikely to discover experiment purpose
Disadvantages
Time consuming
Hard to decide which characteristics to match
