experiments

Question 1

four research methods

Answer 1

laboratory
field
natural
quasi

Question 2

what is a laboratory experiment

Answer 2

a research method conducted in a controlled setting whereby the research manipulates the IV and measures the DV. EV (Exraneous Variables) are controlled

Question 3

2 advantages and 2 disadvantages of a laboratory experiment

Answer 3

+ high control of EVs = means a cause and effect relationship can be established
+ easy to replicate to ensure reliability
- low ecological validity
- demand characteristics likely

Question 4

what is a field experiment

Answer 4

a research method conducted in a natural setting whereby the research manipulates the IV and measures the DV. There is some control of EVs.

Question 5

2 advantages and 2 disadvantages of a field experiment

Answer 5

+ high ecological validity
+ demand characteristics less likely
- low control of EVs - difficult to get a cause and effect relationship
- more difficult to replicate

Question 6

what is a natural experiment

Answer 6

a research method whereby a researcher makes use of a naturally occurring IV (one that is already happening and is not manipulated by the researchers). There is little control of EVs

Question 7

2 advantages and 2 disadvantages of a natural experiment

Answer 7

+ high ecological validity
+ demand characteristics less likely
- no real control of EVs - difficult to get a cause and effect relationship
- more difficult to replicate

Question 8

what is a quasi experiment

Answer 8

an experiment done in any setting where the participants are unable to be randomly allocated because they are automatically assigned to a condition based on a characteristic of them.

Question 9

advantage and disadvantage of a quasi experiment

Answer 9

+ less experimenter bias in allocation of p’s because they are automatically assigned
- might be participant variable EV’s as participants cannot be randomly assigned
