Question 1

Controlled Experiment

Answer 1

Manipulation of an independent variable to test its effect on a dependent variable

Question 2

Controlled experiment advantages

Answer 2

• Controlled environment allows establishment of a cause-effect relationship
• Can be replicated by other researchers
• Standardised procedures reduces bias/subjectivity

Question 3

Controlled experiment disadvantages

Answer 3

• Controlled environment reduces external validity
• Participant expectations can influence behaviour/results

Question 4

Case Study

Answer 4

In-depth investigation into a person, group or phenomena

Question 5

Case study advantages

Answer 5

• In-depth
• Easier to follow over long periods of time
• Allows study of cases where replication may be unethical

Question 6

Case study disadvantages

Answer 6

• Small sample size - difficult to generalise
• Non-replicable
• Time-consuming and resource intensive

Question 7

Modelling

Answer 7

Construction of a physical/conceptual model that represents a system

Question 8

Modelling advantages

Answer 8

• Structured framework
• Helps predict future outcomes/behaviour
• Visual representation of virtual concepts

Question 9

Modelling disadvantages

Answer 9

• May simplify complex reality
• Built upon assumptions

Question 10

Simulation

Answer 10

Using a model to study the behaviour of a system

Question 11

Simulation advantages

Answer 11

• Controlled environment helps manipulate variables
• Can run multiple iterations
• Study unethical/unfeasible situations

Question 12

Simulation disadvantages

Answer 12

• May lack ecological validity due to artificialness
• Ethical considerations
