Types of Experiments

Question 1

Experimental method

Answer 1

Where you manipulate the variables to test cause and effect and to test hypothesis.

Question 2

Strength of experimental method

Answer 2

Objective and more scientific.
Test cause and effect.

Question 3

Weakness of experimental method

Answer 3

Higher chance of demand characteristics.

Question 4

Laboratory experiment

Answer 4

Where the IV is directly manipulated in an artificial and highly controlled setting.

Question 5

Strength of a lab experiment

Answer 5

Less chance of extraneous (situational) variables.
High in internal reliable.
Easier to test cause and effect.

Question 6

Weakness of lab experiment

Answer 6

Lack ecological validity.
Lacks construct validity.
Higher chance of demand characteristics.

Question 7

Field experiment

Answer 7

Where the IV is directly manipulated in a natural environment with some levels of controls.

Question 8

Strength of a field experiment

Answer 8

High in ecological validity.
Less chance of demand characteristics.
High in external validity.

Question 9

Weakness of a field experiment

Answer 9

High chance of extraneous (situational) variables.
Lacks internal reliability and harder to test cause and effect.

Question 10

Quasi Experiment

Answer 10

Where the IV is naturally occurring and takes place in an artificial or natural environment.

Question 11

Weakness of quasi experiment

Answer 11

Time consuming
Lacks internal reliability as you have to wait for IV to naturally occur.

Question 11

Strength of a quasi experiment

Answer 11

Can obtain more natural behaviour.
Higher in ecological validity if in natural environment.
More ethical.
