theorys and methods Flashcards
validity
the extent to which a concept is accurately measured
reliability
the extent to which, we’re the same study to be repeated, it would produce the same result
generalisation
application of the results from a study to the wider target population
ethics
concerned with morality, the standards of behaviour when sociologists carry out research
quantitative data
data that can be counted or measured in numerical values
strengths of quantitative data
• can be generalised for entire populations
•can be compared across population groups
• simple to analyse
• more objective and less open to bias
weaknesses of quantitative data
•much less narrower in meaning and detail
•may fail to represent real life
qualitative data
expressed in words and may take the form of a written description of the thoughts, feelings and opinions of participants
strengths of qualitative data
• more detail, participant has more opportunity to report their feelings
•greater external validity
weaknesses of qualitative data
•more difficult to analyse
•patterns and comparisons are hard to identify
•may rely on subjective interpretations of the researcher, leading to researcher bias
primary data
original data that has been collected specifically for the purpose of the investigation by the researcher
strength of primary data
collected for the purpose of that particular investigation
weaknesses of primary data
•time consuming
secondary data
data that has been collected by someone other than the researcher, this data already exits
strengths of secondary data
•inexpensive and easily accessed
•may find the desired information
weakness of secondary data
•time consuming and costly
•may not be suited to your exact research
practical issues with using methods
•Time available affects choice of method and scale of research.
• Finance affects the size of a research team, the number of respondents who can be contacted and the time available for research to be carried out in.
• Source of funding Research is sponsored by government, local government, businesses, voluntary organisations etc. and will inevitably reflect the concerns of these funding bodies.
• Access and the nature of the research subject Sociologists have to exercise a high degree of sensitivity towards research subjects. Every social actor and social group has both a public and a private face and some may not welcome intrusion into the latter.
• Research opportunity If the research is planned well in advance, any method could be used. Sometimes a research opportunity suddenly appears so the researcher is likely to employ open-ended approaches,
‘going with the flow’ of the research opportunity
key ethical considerations
•informed consent + guardianship
•if consent has not been gained and deception has been used
•The right to withdraw from the research
•Debriefing
•Anonymity and confidentiality
• Privacy
•Differentiation in groups
• Power relationships
• Potential implications of the research
representativeness and generalisations
•Most sociologists want to be able to generalise, the ability to make statements about the whole group, from this sample
• For this to happen, the sample has to be representative of the whole group.
• This means that the sample should have the same characteristics, in the same proportions, as the whole group. If the sample does not reflect the social make-up of the whole population then it will not be representative.
random sampling
where every member of the target population has an equal chance of being chosen.
how:
1. need a sampling frame, a complete list of all members of the target population is obtained.
2.all the names are assigned a number.
3.sample is selected randomly.
opportunity sampling
recruiting anyone who happens to be available at the time of the study, researcher goes somewhere they are likely to find their target population and ask people to take part
voluntary sampling
when people actively volunteer to be in a study by responding to a request which had been advertised by the researcher, participants self select by responding to an advert
stratified sampling
participants are selected from different subgroups in the target population, in proportion to the subgroups frequency in the population
snowball sampling
participants are asked to assist researchers in identifying other potential subjects
structured interview
relies on asking questions in a set order to collect data on a topic
advantages of structured interview
•more reliable as can be easily repeated
• will be a high response rate with more honesty answers - large numbers of people
disadvantages of structured interviews
• the interviewer must persist with set questions even if something interesting comes up
•time consuming and unlikely to get a large sample + interview bias
unstructured interview
an interview with no pre-planned questions
advantages of unstructured interview
•produces qualitative data
•higher validity
•interviews are bale to offer their subjects support and exercise sensitivity
disadvantages of unstructed interview
•time consuming and expensive
•require a skilled interviewer
•produce a large amount of text
•lacks reliability, unscientific
•demand characteristics
