types of experiments

Question 1

describe a laboratory experiment

Answer 1

takes place in an environment where different variables can be carefully controlled

Question 2

give 2 strengths of laboratory experiments

Answer 2

• high degree of control
• replication

Question 3

give 2 limitations of laboratory experiments

Answer 3

• experimenters bias
• low ecological validity

Question 4

describe a field experiment

Answer 4

more natural environment where different variables can be controlled but not a lab

Question 5

give 2 strengths of field experiments

Answer 5

• naturalistic
• controlled IV

Question 6

give 2 limitations of field experiments

Answer 6

• ethical considerations
• loss of control

Question 7

describe a quasi experiment

Answer 7

IV has not been determined by the researcher, it naturally exists eg. gender

Question 8

give a strength of quasi experiments

Answer 8

• controlled conditions, replicable

Question 9

give a limitation of quasi experiments

Answer 9

• can’t randomly allocate ppts to conditions so may be confounding variables

Question 10

describe a natural experiment

Answer 10

IV is not brought about by the researcher but wouldve happened even if the researcher hadnt been there eg. covid

Question 11

give 2 strengths of natural experiments

Answer 11

• provides opportunities that wouldve been imposible due to practical or ethical issues
• high external validity

Question 12

give 2 limitations of natural experiments

Answer 12

• natural occuring events mat be rare so not replicable + hard to generalise
• very difficult to randomise ppts into groups so extraneous variables
