research methods Flashcards
primary sources
first hand data generated by the researcher themselves
- observations
- questionnaires
- interviews
strengths of primary data
- fit for purpose
- researcher is aware of any problems
weaknesses of primary data
- more costly
- more time consuming
secondary sources
involves researcher taking advantage of data which already exists
- official statistics
- public/personal documents
- media
strengths of secondary data
- cost and time efficient
- may be the only source of information for historical topics
weaknesses of secondary data
- not fit for purpose
- researcher unaware of problems with the data
quantitative data
data that revolves around counting or measuring things
- official statistics
- closed ended questionnaires
- experiments
strengths of quantitative data
- fairly easy to analyse with objective procedures
- easy to make comparisons
- usually collected in a systematic, objective way
- can be more representative
- tends to be reliable
weaknesses of quantitative data
- lacks detail
- may not be totally objective if sociologist displays bias
- tends to lack validity
qualitative data
data which takes the form of words
- unstructured interviews
- open ended questionnaires
- participant observation
strengths of qualitative data
- more in depth and detailed insight into meanings and motives
- tends to be more valid
- allows new insights
weaknesses of qualitative data
- lacks reliability
- more difficult to analyse so costly and time consuming
- may be unrepresentative
- it is subjective
factors affecting the choice of a topic
- personal reasons
- availability of data
- funding/policy issues
- interests of society
- theoretical perspective of the researcher
longitudinal research
where individuals are researched at intervals over a long period, sometimes even a lifetime
example of longitudinal study
Parker - studied drug use in a group of 1125 teenagers over 4 years from 14-18 and found that the types of drugs used changed over time and that w/c people experimented from an earlier age but by 18 the m/c had caught up
strengths of longitudinal studies
- can observe changes in a group over time
- eliminates the problem of individual differences
weaknesses of longitudinal studies
- panel attrition (people dropping out)
- keeping in touch with participants
- difficulties of analysing large amounts of data
cross sectional studies
where different groups of individuals are compared at different stages of their lives
- eg compare a group of 15 year olds with a group of 20 year olds with a group of 25 year olds
practical factors of research methods
- time
- cost
- subject matter
- personal characteristics
- hardship/danger
- recording data
ethical factors of research methods
- informed consent
- deception
- privacy
- confidentiality
- harm
- guilty knowledge
theoretical factors of research methods
- validity
- reliability
- representativeness
- positivism v interpretivism
validity
truthful, meaningful and accurate reflection of reality and what it set out to measure
reliability
data is reliable if a piece of research is reproduced with the same methods and findings are consistent and replicable
representativeness
would like research to be representative of wider society, a larger or more diverse group will be more representative
