Research Methods Flashcards
Laboratory Experiments
-favoured by positivists

advantages of laboratory experiments
-highly reliable,
disadVantages of laboratory experiments
-the Hawthorne effect (a lab is not a formal or natural environment)
-ethical issues (reseacher needs informed consent of the participants
