Types of Experiments Quiz

Why can cause and effect be established in lab experiments?

• Because variables can be controlled

• Because experiments are conducted in natural settings

• Because they involve large sample sizes

• Because they rely on observational data

In a lab experiment, how should participants be allocated to the experimental conditions?

• Random allocation

• Systematic allocation

• Self-selection

• Based on age

Apart from being well controlled, what is another strength of the lab experiment?

• High internal validity

• Low cost

• Natural setting

• Long duration

What are the two weaknesses of the lab experiment?

• Lack of ecological validity and ethical concerns

• High cost and time-consuming

• Limited sample size and lack of control

• Difficulty in replication and lack of precision

Why are demand characteristics more likely to occur in a lab experiment?

• Because participants are aware they are being studied

• Due to the controlled environment

• Because of the presence of a researcher

• All of the above

Where is a field experiment conducted?

• In a laboratory

• In a controlled environment

• In a natural setting

• In a virtual simulation

What is a disadvantage of a field experiment compared to a lab experiment?

• Less control over variables

• Higher cost

• Limited sample size

• More ethical concerns

What ethical issues might occur in a field experiment

• Informed consent may not be obtained from participants.

• Participants may be exposed to harm or discomfort.

• Privacy and confidentiality of participants may be compromised.

• There may be a lack of transparency about the experiment's purpose.

What type of validity is higher in a field experiment than a lab experiment and why?

• Internal validity, because field experiments have more control over variables.

• External validity, because field experiments are conducted in natural settings.

• Construct validity, because field experiments better measure theoretical concepts.

• Statistical validity, because field experiments have larger sample sizes.

What is the difference between a field experiment and a Quasi experiment?

• In a field experiment the IV is manipulated by the researcher whereas Quasi the IV is an individual difference and not controlled by the researcher

• Field experiments lack random assignment, while quasi-experiments are conducted in natural settings.

• Both field and quasi-experiments are conducted in controlled environments.

• Field experiments and quasi-experiments both involve random assignment.
