Experimental Method Flashcards
1
Q
Laboratory Experiment
A
Conducted in highly controlled environment where extraneous and confounding variables are regulated
2
Q
Field Experiment
A
Experiment that takes place in a natural setting, researcher manipulates the IV, records the effect of the DV.
3
Q
Natural Experiment
A
Where the IV is not brought about by the researcher but would have happened if the researcher had not been there.
4
Q
Quasi Experiment
A
IV has not been determined by anyone, variables simply exist. IV occurs naturally and the participants cannot be randomly allocated.
5
Q
Strengths and Weaknesses of Laboratory Experiment
A
- Maximum control over EV’s and CV’s
- Replication is more possible
- May lack generalizability
- Demand Characteristics may occur
6
Q
Strengths and Weaknesses of Field Experiment
A
- More natural experiment
- Participants are unaware they are being studied
- More difficult to control extraneous variables
- There are ethical issues
7
Q
Strengths and Weaknesses of Natural Experiment
A
- May be the only ethical option
- Greater external validity
- Naturally occurring event may only happen very rarely
- Participants are not randomly allocated
8
Q
Strengths and Weaknesses of Quasi Experiment
A
- There is often high control
- Comparisons can be made between people
- Cannot randomly allocate participants to conditions
- Casual relationships cannot be established
