Explain and evaluate the main sociological research methods and their ethical issues

What this dot point is asking

This dot point asks you to understand how sociologists actually produce knowledge: the main research methods, the theoretical debate about what counts as good evidence, and the practical and ethical issues researchers face. The internal assessment in TASC Sociology requires you to plan and conduct your own inquiry, so these skills are assessed directly, not just described.

Positivism versus interpretivism

The methods debate rests on two traditions. Positivism, associated with Emile Durkheim, treats sociology like a natural science: it seeks objective, measurable social facts and looks for patterns and cause-and-effect relationships. Durkheim's study of suicide used official statistics to argue that suicide rates were caused by levels of social integration, not individual psychology. Positivists prefer quantitative data because it is reliable and can be generalised.

Interpretivism, influenced by Max Weber's concept of verstehen, argues that humans are not like objects: they attach meanings to their actions. To understand society we must see the world through people's eyes. Interpretivists prefer qualitative methods that produce valid, detailed insight into meaning, even if the data is harder to repeat.

Primary quantitative methods

• Social surveys and questionnaires gather standardised data from many people, so they are reliable and representative, but closed questions can miss meaning.
• Structured interviews ask every respondent the same fixed questions, improving reliability.
• Experiments are rare in sociology because society cannot be controlled like a laboratory, though field experiments are sometimes used.

Primary qualitative methods

• Unstructured interviews allow the researcher to follow up answers, producing valid, deep data but low reliability.
• Participant observation involves joining a group to study it from the inside; it can be overt (the group knows) or covert (hidden). It gives rich insight but raises ethical problems and is hard to repeat.
• Case studies focus in depth on one group or community.

Secondary data

Sociologists also use existing sources: official statistics from the Australian Bureau of Statistics, the Census, documents, and media content analysis. These are cheap and large-scale, but were not collected for the research and may be biased or incomplete.

Ethics

Sociological research must protect participants. Key principles are informed consent, confidentiality and anonymity, avoiding harm, and the right to withdraw. Covert observation is controversial because participants cannot consent. Australian universities require research to pass a human research ethics committee, reflecting national ethical guidelines.

When you design your own internal investigation, you will choose a method, justify it against reliability, validity, representativeness and ethics, and acknowledge its limitations. That justification is exactly what the assessment criteria reward.
