Experiments
Ethical
Challenges:
- often no consent due to large scale, deception
- one/more group being disadvantaged by experiment
- consequences of experiment, you could cause issues
Strengths:
- no informed consent but that does mean no emotional harm if the participants are unaware (often)
Painter and Farrington experiment, and Rosenthal and Jackson experiment, one group disadvantaged
Practical
Challenges:
- need authorities to agree with it (gatekeepers)
- time consuming
- data gathering / processing is hard on large scale
Strengths:
- don't have to set things up
- no need to get a sample
- some cases don't have gatekeepers
Brown and Gay experiment, no gatekeepers
Theoretical
Challenges:
- validity, artificial so lacks ecological validity
- Hawthorne effect
- representativeness, small sample size
- generalisability (cannot do as experiment small)
- objectivity (hypothesis testing, trying to prove what you think)
Strengths:
- reliability (standardised method, replicable)
- manipulating variables
- reduced extranous variables
-
Ethical
Challenges:
- emotional impact / traumatising
- issues of consent, informed consent will invalidate research
Strengths:
- consent gained face-to-face (could be informed consent)
- can guarantee rights
- can be anonymous
-
Theoretical
Challenges:
- hard to replicate due to extraneous variables
- poor reliability
- objectivity (hypothesis testing)
Strengths:
- ecological validity is very strong
- no 'Hawthorne effect'
- high representativeness due to large sample size
- higher generalisability
- can manipulate variables
Practical
Challenges:
- persuading people to give up their time, need to get a sample/participants
- costly do to
- can be time consuming
Strengths:
- facilities and space needed is not too challenging as it is small scale
- could be little time needed
Field experiments
- sociology favours field experiments more than laboratory ones
- often no consent
- often macro-scale
- can be control vs experiment group
- no artificiality
Laboratory Experiments
- point of a lab experiment is to find out the causation
- hypothetsis testing
- have an experimental and a control group (comparative method) (compare independent variable to see results of dependant)
