What is an experiment in sociology?
A method where researchers control variables to test cause-and-effect relationships.
What is the independent variable (IV)?
The variable the researcher changes.
What is the dependent variable (DV)?
The variable that is measured.
What is the main aim of experiments?
To establish causation (cause and effect).
What is a laboratory experiment?
An experiment conducted in a controlled, artificial environment.
Give an example of a lab experiment.
Stanley Milgram – obedience study.
One strength of lab experiments?
High reliability (easy to replicate).
One weakness of lab experiments?
Low ecological validity (unnatural setting).
What is a field experiment?
An experiment conducted in a real-life setting.
Give an example of a field experiment.
Rosenthal and Jacobson – teacher expectations study.
One strength of field experiments?
High validity (realistic behaviour).
One weakness of field experiments?
Less control over variables.
What is a natural experiment?
An experiment where the IV occurs naturally.
Strength of natural experiments?
Useful when unethical/impossible to control variables.
Weakness of natural experiments?
Low control → difficult to prove causation.
What is validity?
Whether the study measures what it intends to.
What is reliability?
Whether the study can be repeated with similar results.
Why do positivists support experiments?
They are scientific, reliable, and objective.
Why do interpretivists criticise experiments?
They lack validity and don’t reflect real behaviour.
How are experiments used in education research?
To study labelling and teacher expectations.
