Theory & Methods Although there are no hard and fast rules about which methods are best, some have become associated more with a positivist approach (experiments, questionnaires) and some with social action approaches (participant observation) Theory & Methods In order to find out information about society sociologists use a range of research methods. Theory & Methods Primary Methods Refers to information collected by the researcher It did not exist before Theory & Methods Secondary Methods Refers to data which already exists Theory & Methods Type Of Data Primary Theoretical Perspective quantitative Experiments Positivist qualitative Observation Interpretivist Surveys: Questionnaires Positivist qualitattive Surveys: Interviews Interpretivist quantitative Official Statistics Positivist qualitative Mass Media, Diaries Interpretivist quantitative Secondary Method Quantitative data Data in numerical form – statistics Tables etc can be made of them Helpful for looking at correlations/relationships between factors e.g Durkheim and suicide rates in different countries Often seen as more reliable data than qualitative Qualitative Data Data in word form Harder to analyse than stats Often seen as more valid data than quantiative Validity i.e how true a picture does the data give how close to real life is it? Reliability Data is reliable when different researchers can repeat the research – using the same methods and getting the same results The Research Process 1. Choose a topic At A2 you will carry out a research study of your own choosing. Which topic you choose will depend on a number of factors. Sociologists in their research will go through the same process Values of researcher What they see as important e.g gender issues in education their beliefs, interests etc Value of society What society sees as important e.g. Feminists looking at increasing female crime etc Funding Practical issues are very important How much money and where the money comes from often dictate what you can and can’t do e.g. The Joseph Rowntree Foundation funds a lot of research http://www.jrf.org.uk Availability of data How easy is it to get access to what you want to find out? e.g some areas of crime Theoretical position Marxists will be keen to study areas of class conflict Post-Modernists may look at the fragmentation of society etc The Research Process 2. Choosing Research Methods Some methods are more suitable for particular types of research Participant Observation may be more useful than a questionnaire when studying football hooliganism But if the group is large a questionnaire may be more appropriate The Research Process 3. Theoretical Considerations Positivists have tended to prefer methods which generate quantitative data This is because they believe in a scientific study of society Quantitative data is seen as more objective/unbiased e.g Durkheim and suicide The Research Process 3. Theoretical Considerations Interpretivists are more interested in in-depth studies. These enable the researcher to see the action through the eyes of the participants They prefer qualitative methods which give a deeper insight into the meanings behind human interaction e.g. Atkinson and suicide The Research Process 3. Theoretical Considerations However this does not mean that positivists will only use quantitative methods and vice versa! Ethical Issues Ethical issues are moral principles (beliefs about what is seen as right and wrong). These set down important guidelines for research – stating what you can and can’t do. There are many grey areas in sociological research and consequently the British Sociological Association has set down key principles (other countries have done the same as have other subject areas - e.g. Psychology) Ethical Issues Informed Consent Researchers should give the respondents full info about the research The respondent then knows what they are agreeing to Ethical Issues Deception This is where the respondents are kept from knowing the true purpose of the research Sometimes this is done so that people will act naturally e.g. covert observation But it could be accused of spying Ethical Issues Confidentiality Identity of participants should always be kept secret Unless there are very good reasons for not doing so Ethical Issues Privacy Although privacy should be respected Most research intrudes into people’s lives Although many give their consent – some participants find that the research has been too intrusive Laboratory Experiments Lab experiments are the backbone of scientific discovery The psychologist Milgram used an experiment to discover how cruel humans can be to each other Lab experiments are rare in sociology Laboratory Experiments Controlling variables Labs help to isolate which variables affect something the most E.g Plant growth can be affected by light, water and temp In society it is almost impossible to control variables Laboratory Experiments Quantifying Results Experiments usually give quantifiable data They also allow replication – others can do the experiment and get the same results Laboratory Experiments Correlation and causation Labs help to find which variables are linked and how. Is water more important than light for a plant’s growth? Laboratory Experiments Lab experiments and people Sociologists are sceptical of lab experiments involving people Variables can’t be controlled People will not act naturally Society could be said to be the lab for sociologists Field Experiments Lack of control Field experiments are conducted in normal everyday situations e.g. in a classroom Variables can’t be controlled and results can be seen as inexact Field Experiments The ‘Hawthorne Effect’ This means that the respondents behave in a certain way because they are being observed Comes from 1930’s Chicago study at the Hawthorne Electrical works They found that respondents felt special because they were being watched. Field Experiments Experimenter Bias People may respond differently to a male/female, old/young person etc This is an unintended affect Field Experiments Ethical Issues This questions whether it is right or wrong to experiment on individuals It depends on the experiment but the BSA and BPA say that subjects should be told afterwards that they have taken part in an experiment Surveys Surveys involve systematic collection of data from a large number of people. They usually use questionnaires and/or interviews but because of their scale are more likely to use closed questions giving quantitative data. Surveys Response To Surveys Response rates in surveys are typically low – unless it is something like the National Census where everybody is supposed to take part. Reasons offered for non response include: No time No interest Unable to contact (moved away) Suspicious of research • Maintaining privacy Sampling Sampling is extremely important in sociological research. Given the practical constraints of time and money, it is impossible to approach everyone on a given subject. As a result, a smaller number is taken from the population, the important thing being that this small group is typical (representative) of the larger group. Sampling Sampling Unit This is the individual sample taken from a population e.g. a doctor from a list of doctors in Torbay Sampling Sampling Frame This is the list of the population to be studied and from where the sample is chosen e.g. List of doctors in Torbay Electoral registers, school registers, telephone books etc are often used as sample frames Types Of Sample Random Every member of the sampling frame has an equal chance of being selected This avoids bias in selection Types Of Sample Systematic A variation on random where every nth person is chosen from a list e.g. every 10th person on a school register Like with random sampling this does not guarantee representativeness Types Of Sample Stratified Where the population is divided according to certain criteria e.g gender, age etc. Then proportionate samples are taken from each grouping/strata Types Of Sample Where a certain quantity of individuals with certain characteristics are required e.g. 40 women under 30yrs often used in market research not particularly representative Types Of Sample Snowball and Volunteer Snowballing – researcher finds one individual who then puts them in touch with others Often used when it is difficult to find a sample with the right characteristics e.g criminals Volunteers – where individuals are invited to take part in a study e.g press advert both the above are not very representative
