Types of experiment

Question 1

What is a field experiment

Answer 1

• takes place in a natural setting within which the researcher manipulates the IV

Question 2

What is a natural experiment

Answer 2

• where the change of the IV is not done by the researcher but happens naturally

Question 3

What is a quasi-experiment

Answer 3

• almost an experiment but lacks key ingredient, IV is not determined by anyone, the variables simple exist
• strictly speaking this is not an experiment

Question 4

What is a lab experiment

Answer 4

• an experiment that takes place in a controlled environment

Question 5

1- What is a strength of lab experiments

2- What is a limitation of lab experiments

Answer 5

• high control over extraneous variables, high internal validity, replication is more possible
• lack generalisability, low external validity, higher chance of demand characteristics, low mundane realism due to artificial tasks

Question 6

1- What is a strength of field experiments

2- What is a limitation of field experiments

Answer 6

• higher mundane realism, high external validity
• loss of control over ev, precise replication is often not possible, important ethical issues, ppts cannot give consent may be invasion of privacy

Question 7

1- What is a strength of natural experiments

2- What is a limitation of natural experiments

Answer 7

• high external validity, take on more uncommon experiments

- reproduction of study is hard, not generalisable

Question 8

1- What is a strength of quasi-experiments

2- What is a limitation of quasi-experiments

Answer 8

• controlled conditions, share strengths of lab experiments

- cannot randomly allocate ppts, therefore there may be confounding variables
