research methods Flashcards
what is primary data?
data collected on your own
what is secondary data?
using other people’s data for your own purposes
what is quantitative data?
numerical data
what is qualitative data?
written data
what are the practical factors influencing choice of methods?
1.time and money
2.requirements of funding bodies
3.personal skills and characteristics
4.subject matter
5.research opportunity
what are the ethical factors influencing choice of methods?
1.informed consent
2.confidentiality and privacy
3.harm to participants
4.vulnerable groups
what are the theoretical factors influencing choice of methods?
1.validity
2.reliabilty
3.representativeness
what does validity mean?
how truthful the data is
what does reliability mean?
is it repeatable data?
what does representativeness mean?
is the data generalized? e.g mixture of ages and ethnicities
what are the positivists views?
- prefer quantitative data
- see sociology as a science
- they like their research to be reliable and representative
examples of positivists
functionalists: durkheim, parson
marxists: althusser, bowles and gintis
what are the interpretivists views?
- prefer qualitative data
- reject the idea of sociology being a science
- they value validity
examples of interpretivists
interactionalist: becker
what are the different types of sampling?
1.random sampling
2.quasi-random sampling
3.stratified random sampling
4.quota sampling
5.snowball sampling
6.opportunity sampling
what is random sampling?
randomly selecting participants e.g out of a hat. each member of the target population have an equal chance of being picked
what is quasi-random sampling?
a probability sampling method where researches select members of the population at a regular interval
what is stratified random sampling?
method of sampling that involves the splitting of groups into sub-groups and then splitting them groups into even smaller groups
what is quota sampling?
picking the people with the characteristics you want
what is snowball sampling?
where existing study subjects recruit future subjects from other people
what is opportunity sampling?
where the researcher selects participants based on their availability
what is meant by objective?
a researcher must not allow there thoughts and opinions to impact their research findings
what is meant by subjective?
opinions based on personal impressions that are influenced by bias
what are official statistics?
a set of numerical data collected by the government and associated government agencies
practical advantages of lab experiments
funding bodies - fund the experiments
personal characteristics - dont need characteristics as they are detached
easy - sociologist just needs to follow instructions
ethical advantages of lab experiments
informed consent - requirement for funding
legality - rarely ask participants to do anything illegal
theoretical advantages of lab experminets
reliability - easy to replicate as in a controlled environment
practical disadvantages of lab experiments
sample size - difficult to investigate large sizes
time - some people have work, school etc
money - its in a controlled environment
ethical disadvantages of lab experiments
deception - participants don’t get told everything
harm - harmful activities could take place
theoretical disadvantages of lab experiments
validity - information isn’t detailed enough
representativeness - the sample size is too small
practical advantages of field experiments
sample size - large sample sizes making it more representative
money - cheaper as setting is natural
ethical advantages of field experiments
confidentiality and privacy - when collecting any identities as its all kept safe
unintrusive - done without people having to change their daily routines
theoretical advantages of field experiments
validity - information is detailed
representativeness - its a large sample size
practical disadvantages of field experiments
time - takes a long time to gain the right outcome
cant control variable and environment as its real
ethical disadvantages of field experiments
consent - subjects aren’t usually aware they are being studied, so need consent
covert - the participants aren’t aware
