define validity
the extent to which a test measures what it claims to measure
define reliability
the consistency of a research study or measuring test.
define representativeness
the extent to which a sample mirrors a researcher’s target population and reflects its characteristics.
define generalisability
the extent to which the findings of a study can be applied to other situations.
define value freedom
refers to the ability of researchers to keep their own biases and opinions out of the research which they are conducting.
positivism key concepts
scientific principles - "the science of society" observable phenomena - correlation and cause directly measurable - objectivity reliability - rigorous research quantifiable data social facts causal relationship Patterns + trends Value freedom
define researcher imposition
when researcher unintentionally impose their own views or frame work on the people being researched and don’t really get at what respondents think.
strength of the positivism theory
+ objective and scientific approach - free from bias and own values - use quantitative research
+ government more likely to fund studies as it can be generalised and aren’t bias
+ more reliable as is scientific
weakness of positivism
- ignore the subjective experience of an individual
- researcher imposition
interpretivists key concepts
subjective - meaning and experiences of individuals
verstehen and empathy
research imposition - having an option the research
rapport
qualitative data - feelings, meanings and experiences
high validity results - detailed and in-depth
interpretation
strengths of interpretivism
+ high validity (personal experiences and feelings on topic)
+ good for sensitive topics
+ more meaningful
+ reflexivity - aware of own bias and conflicting it
weaknesses of interpretivism
- unsystematic - snowball effect
- research influence and narrow focus ( interpretivist believe this is okay )
- unrepresentative (small sample and individual cases) and narrow focus
- reliability not guaranteed ( interpretivist believe this is okay )
- researcher bias
ethnographic studies
researcher inserts themselves into the natural setting of the social group being studied
observe daily activities
research design - informal or unstructured interviews also used + empathesis with people
strengths
strength of ethnographic studies
+interpretivists support this method (reliable results)
+ detailed qualitative data provided
+ high in validity
+ learn about cultures
weakness of ethnographic study
- researcher bias and influence
- time consuming
- need a well-trained researcher
- ethical issue with illegal behavior (research + participant)
what is respondent validity
A method used by sociologists to double-check validity of behaviour they might have observed.
It checks whether the sociological interpretation of why such attitudes have been expressed in a questionnaire or interview is supported by those who expressed such attitudes
what does respondent validity aim to do
It aims to address problems of interpretation by the researcher that potentially undermines validity.
It aims to therefore improve the authenticity of the data collected by asking the respondents if the researcher’s interpretation of their attitudes/behaviour equates with reality.
A researcher may do this through a follow up informal conversation
what approach is most likely to use respondent validity
Interpretivists are most likely to use this method because the type of research they favour (qualitative) is very much open to interpretation and can therefore be prone to researcher bias or misinterpretation.
longitudinal study
a study carried out over a long period of time or a number of years. this can be continually (observation) or on annually basis (questionnaire, survey, interview)
strength of longitudinal studies
+provide a clear image of the change in attitudes and behaviors over a number of years
weakness of longitudinal studies
- participants may drop out or researchers may loss track of them = undermine representatively of original sample.
- remaining sample = different to those how dropped out = undermine reliability and validity
- positivists = research team become to close to the sample = loss of objectivity
primary research
a methodology where researchers collect data directly, rather than depending on data collected in previous research
secondary data
a research method that involves using already existing data. usually by non-sociologists such as the government
theoretical factors - effecting research methods
positivism or interpretivism
quantitative or qualitative results
