Types of experiments

Question 1

What is the definition of lab experiments

Answer 1

These are highly controlled experiments which make cause and effect easy to establish between the IV and DV

Question 2

Strengths of lab experiments (cr)

Answer 2

control and can be replicated

Question 3

Weaknesses of lab experiments

Answer 3

demand characteristics and experimenter bias

Question 4

What is the definition of field experiments?

Answer 4

These are experiments carried out in a natural setting where the researcher manipulates the IV to see the effect on the DV.

Question 5

Strengths of field experiments?

Answer 5

High ecological validity

in a cover exp it has less likelihood of demand characteristics

Question 6

weaknesses of field experiments?

Answer 6

less control on extraneous variables - hard to establish cause and effect.
difficult to replicate - less reliable data
lack of informed consent - if covert

Question 7

What is the definition of a natural/quasi experiments?

Answer 7

Experiments which are conducted everyday life but the experimenter does not have control over the independent variable because it occurs naturally

Question 8

examples of natural/quasi IV

Answer 8

gender, age, ethnicity

Question 9

strengths of natural/quasi experiments?

Answer 9

less likelihood of demand characteristics
high ecological validity
when covert, high internal validity

Question 10

weaknesses of natural/quasi experiments?

Answer 10

more expensive and time consuming than lab experiments.
no control over extraneous variables that might bias the results.
Hard for researcher to replicate study
