Experimental Designs Flashcards
1
Q
What is repeated measures?
A
An experiment that uses one group of participants but exposes them to two different conditions, they are compared against themselves
2
Q
What are 2 strengths of repeated measures?
A
- Need fewer participants
- Counterbalance order effects
3
Q
What are 2 weaknesses of repeated measures?
A
- May do better on a second test due to ‘practise effect’
- May do things worse due to order effects
4
Q
What is independent measures?
A
Two or more separate groups are tested, one condition for each
5
Q
What are 2 strengths of independent measures?
A
- Control extraneous variables that might be due to having practise
- Less chance of order effects
6
Q
What are 2 weaknesses of independent measures?
A
- Need twice as many participants because there is more than one group
- Participant variables/individual differences
7
Q
What is matched pairs?
A
Having two or more groups of participants where you match participant 1 in group A with participant 1 in group B
8
Q
What is a strength of matched pairs?
A
- Controls some participant variables
9
Q
What is a weakness of matched pairs?
A
- Very time consuming to match participants
