Types Of Experiments

Question 1

Lab strengths

Answer 1

High levels of control , extraneous variables avoided , measure the effect on the DV infer cause and effect
Highly reliable - high levels of control - standardised procedure making it easy to repeat

Question 2

Lab weaknesses

Answer 2

Low in ecological validity - hard to generalise results
Demand characteristics or responds to social desirability bias
Low in mundane realism not representative of task completed in everyday life

Question 3

Field explanation

Answer 3

Conducted in pps own environment

Question 4

Field strengths

Answer 4

High ecological validity

No demand characteristics

Question 5

Field weaknesses

Answer 5

Can’t fully control the situation for IV to measure the effect on the advice therefore not infer cause and effect - extraneous variables
Not reliable not standardised procedure
Ethical issues

Question 6

Quasi explanation

Answer 6

IV is naturally occurring and therefore not manipulated

Question 7

Quasi strengths

Answer 7

IV not manipulated - more ecologically valid

Question 8

Quasi weaknesses

Answer 8

May have low sample not representative to target population , long time to find recruit pps

Question 9

Laboratory explanation

Answer 9

Conducted in highly controlled conditions and usually in laboratory settings
