1
Q
A strength of independent groups
A
No order effects - participants only tested once - can’t practise or become bored/tired - controls important CV
2
Q
A weakness of independent groups
A
More participants - need twice more than RM for same data - expensive - takes time
3
Q
A strength of repeated measures
A
Participant variables - person in both condition - same characteristics - controls important CV
4
Q
A weakness of repeated measures
A
Order effects - participants getting better/worse - doing similar task twice - reduces validity
5
Q
A strength of matched pairs
A
No order effects - only tested once - no practice - enhances validity
6
Q
A weakness of matched pairs
A
More participants - need twice participants as RM for same data - more time - expensive
