Research Methods Flashcards
Laboratory Experiments
-favoured by positivists
-highly controlled environment
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
field experiments
-take place in real social world
-those involved are usually unaware of the research taking place
advantages of field experiments
-less artificiality
-validity ( people are unaware of the experimental situation
disadvantages of field experiments
-ethical issues ( experiment carried out on people without their informed consent)
-limited application
structured interview
- positivist favoured method
-face to face or over the phone
advantages of structured interview
-practical(easy and cheap to administer)
-reliable (structured process provides a recipe for reproducibility)
-quantifiable because they use close ended questions
disadvantages of structured interview
-lack of validity: people may lie or exaggerate
-+ the use of close ended questions can restrict information
unstructured interview advantages
-flexibility (the interviewer is not restricted to a fixed set of questions
-valid (people can be open and truthful due to opened ended questions
unstructured intervierws
-interpretivist favoured
method
-open ended question
unstructured interview disadvantage
-practical ( time consuming and costly due to interview training)
-unrepresentative ( small research samples)
-not reliable (due to how the questions are open)
questionnaires
-favoured by positivists
-via post email or handed out in person
questionnaires advantages
-practical (cheap and quick)
-quantifiable data
-representative (reach a geographically widespread research sample
questionaires disadvantages
-response rate (postal questionnaires in particular is very low)
-low validity (people may be more willing to lie)
-unrepresenative (people are too busy)
observations
-either be participant or non participant (meaning researcher is involved in one)
participant observations (researcher joins in the activities of the group they are researching) advantages
-valid (groups are observed in a natural settings + detailed data
disadvantages of participant observation
-unreliable (open ended questions cannot be replicated)
-unrepresentative (small scale groups)
-not valid (Hawthorne effect)
non participant observation
- the observer avoids any direct involvement with the researchers group
advantages of non participant observation
valid- limited risk of the researcher going native
disadvantages of non participant observation
not reliable
-not representative (involves a small scale sample )
overt observations
the researcher explains their research intention to the group so participants are aware
overt observation pros
-less ethical issues that covert as participants know they are being researched
-higher level of reliability than covert
overt observation cons
-practical (time consuming)
-lacks validity (Hawthorne effect)
-less reliable (difficult to repeat )
