what is a field experiment?
the aim of field experiment
to obtain some control while avoiding the artificiality of the laboratory
example of field experiment
Rosenhan’s ‘being sane in insane places’
practical
(-) less control over variables because they don’t meet the rigorous scientific criteria of the lab experiment since sociologists cant control all variables.
(-) only few situations that can be adapted to become a field experiment
ethical
(-) researchers don’t usually gain informed consent from participants because it would ‘give the game away’ (hawthorne effect)
validity
(+) less artificiality because it is set in real world situations
(+) people are often unaware of the experimental situation so they will act normally so their reactions are genuine
(-) only measure what people don’t know why they do it which might compromise their validity
reliability
(-) created/adapted from a real life setting so it lack of control meaning its difficult to replicate.
representativeness
(-) involve smaller samples of participants which makes it difficult to generalise the results to the wider population.
why do Interpretivists prefer field experiments?
why do Positivists criticise field experiments?
