experimental design Flashcards
1
Q
What is experimental designs?
A
How to allocate your participants to different conditions
2
Q
What are the three experimental design?
A
- Independent groups
- Repeated measures
- Matched pairs
3
Q
Describe the independent measure:
A
- Recruit group of participants
- Randomly allocate to conditions
- Measure the DV for each group
- Compare the results for the two groups
4
Q
Strengths of independent measures:
A
- No order effects
- Reduced demand characteristics
5
Q
Limitations of independent measures:
A
- Participant variables
- More participants needed
6
Q
Describe the repeated measures:
A
- Recruit a group of participants
- Does condition one, then conditions two
- Compare the results for the two conditions
7
Q
Strengths of repeated measures:
A
- Reduced participant variables
- Fewer participants
8
Q
Limitations of repeated measures:
A
- Order effect e.g boredom
- Rise in demand characteristic
9
Q
How to eliminate limitations of independent measures?
A
Randomly allocated to conditions to avoid bias
10
Q
How to eliminate limitation of repeated measures?
A
- Counterbalancing
- Single blind technique
11
Q
Describe the matched pairs:
A
- Recruit a group of participants
- Find there personality
- Find similar people
- Pair them together
- Separate them into each condition
- Compare the results of the matched pairs
12
Q
Strengths of the matched pairs:
A
- Participant variable reduced
- No order effect
13
Q
Limitations of the matched pairs:
A
- Matching is not perfect
- More participants required
- Time consuming
14
Q
How to eliminate limitations of matched pairs?
A
- Use identical twins in different conditions
- Already closely matched
