AQA GCSE Sociology (8192): Sociological research methods – Revision Notes

These notes condense the research methods study guide; go there for full explanations and worked paragraphs.

They cover section 3.7, Sociological research methods, of the AQA GCSE Sociology (8192) specification, Version 1.2 (June 2026), for GCSE exams 2019 onwards: research design, qualitative and quantitative methods, different types of data, primary and secondary sources, interpretation of data, practical issues and ethical issues. Methods are not a separate paper. Paper 1 (The sociology of families and education) and Paper 2 (The sociology of crime and deviance and social stratification) both assess “relevant areas of social theory and methodology”, so expect methods questions set in any topic.

When you have revised, try the research methods practice questions. Track your progress on the AQA GCSE Sociology hub and the 8192 checklist. The older research methods overview is a one-page summary.

What the specification asks you to do

• Identify, describe and explain methods and methodological issues.
• Explain advantages and disadvantages of a method for a specific area of research.
• Understand research design, including practical difficulties and ethical issues.
• Judge the relevance and usefulness of primary and secondary sources.
• Interpret data in a variety of forms.

Focus group	Qualitative	Shows how views form in discussion	One person can dominate	Parents’ views on school choice
Participant observation	Qualitative	Sees real behaviour	Time; observer effect; ethics if covert	Pupil subcultures
Non-participant observation	Qualitative or quantitative	Researcher stays detached	Group may act differently when watched	Classroom interaction
Official statistics	Quantitative, secondary	National, regular, free	Definitions set by government; unrecorded events	Exam results by gender over time

Studies at a glance (methods focus)

All details below are as the specification’s Appendix B summarises them.

Who	What they did	Finding (in brief)	One methods evaluation point
Ball (1981)	Three years as participant observer in a south coast comprehensive	Raised questions about selection and socialisation in banded and mixed ability cohorts	One school: rich detail, limited generalisation
Willis (1977)	Observation, participant observation, group discussions, informal interviews, diaries; Midlands school	Counter culture among working-class boys	Saw school from students’ view; small group
Halsey, Heath and Ridge (1980)	Sample of over 8,000 males born 1913-1952	Clear class inequalities in staying on and university	Excluded females
Carlen (1988)	Unstructured interviews with 39 women aged 15-46	Crime more likely when the class and gender deals fail	Relatively small sample
Townsend (1979)	Questionnaires to over 2,000 households, more than 6,000 individuals; deprivation index	More than 22% in poverty in 1968-69 on his measure	Index items may show choice, not poverty
Young and Willmott (1973)	Large-scale survey: nearly 2,000 people interviewed in Greater London and surrounding areas	Symmetrical family	Feminists questioned whether “symmetry” existed
Devine (1992)	Interviews with Vauxhall Luton workers and their wives, late 1980s	Did not find evidence to support privatised instrumentalism	Revisiting the same site allowed comparison over time

Must-know distinctions

• Reliability vs validity. Reliable = repeatable. Valid = true to life. Questionnaires lean reliable; unstructured interviews and participant observation lean valid.
• Aim vs hypothesis. An aim is broad; a hypothesis predicts and can be tested.
• Random vs representative. Random describes how people are chosen; representative describes the result.
• Quota vs snowball. Quota fills set numbers for each group; snowball grows through contacts.
• Overt vs covert. Overt risks the observer effect; covert risks breaking informed consent.
• Primary vs secondary. Who collected the data, and for what purpose.
• Official vs non-official statistics. Who produced the figures, not whether they are accurate.
• Mixed methods vs triangulation. Mixed methods combines quantitative and qualitative; triangulation checks findings across methods or sources.
• Practical vs ethical issues. Practical = time, cost, access. Ethical = consent, confidentiality, harm.
• Percentage vs percentage points. 20% to 30% is a 10 percentage point rise, which is a 50% increase.

Mini essay plan

Typical extended question: “Discuss how far participant observation is the best method for studying processes within schools.”

1. Define and apply. Participant observation: the researcher joins the group. In a school this means sitting in lessons or spending time with pupils.
2. For (validity). Records what pupils and teachers do, not what they claim. Ball’s three years in one comprehensive and Willis’s observation of working-class boys in a Midlands school show banding, teacher expectations and counter culture as they happen.
3. For (hard-to-reach views). Pupils resistant to school may not answer a questionnaire honestly; trust built over time gets beneath the surface.
4. Against (practical). Time and access: the head teacher usually has to agree; an adult cannot pass as a pupil, so covert work is rarely possible.
5. Against (reliability and representativeness). One school or class cannot be repeated or generalised.
6. Against (ethics). Pupils are under 18: parental consent, confidentiality of named teachers, harm from being labelled in a report.
7. Alternatives. Questionnaires on setting and self-image give comparable data across many schools; official statistics show attainment by set or exclusion rates.
8. Judgement. Best for why and how; weaker for how common. A mixed methods design is likely to be most useful.

Quick self-test

1. Define a hypothesis.
2. What is the main purpose of a pilot study?
3. A researcher picks every 20th pupil from a school list. Which sampling method is this?
4. Which sampling method would suit a study of people in an unlicensed street-racing scene, and why?
5. Give one strength of closed questions.
6. What is the difference between participant and non-participant observation?
7. Name the three practical issues listed in the specification.
8. Name the three ethical issues listed in the specification.
9. Give one way to protect confidentiality.
10. A fictional researcher posts 400 questionnaires and receives 112 back. What is the response rate?
11. Why might official statistics on a topic change even if behaviour does not?
12. Is a researcher’s own interview transcript primary or secondary data?

Answers

1. A testable statement predicting a relationship between two things.
2. To test the method on a few people and fix problems before the main study.
3. Systematic sampling.
4. Snowball sampling: there is no sampling frame, and members can introduce the researcher to others they trust.
5. Answers are easy to count and compare, so results are reliable.
6. In participant observation the researcher joins the group; in non-participant observation they watch without joining.
7. Time, cost and access.
8. Consent, confidentiality and harm to participants.
9. Anonymise names and places, or store data securely.
10. 112 / 400 x 100 = 28%.
11. A change in definitions, recording rules or reporting can change the figures.
12. Primary data.

Where marks are usually lost

• Giving a general strength of a method without linking it to the topic in the question.
• Writing “random samples are representative” instead of “give everyone an equal chance”.
• Mixing up reliability and validity, or using “valid” to mean “good”.
• Calling unstructured interviews quantitative because they can be large-scale.
• Forgetting to show working in a percentage calculation, or giving no units.
• Describing the trend in a table without quoting any figures.
• Answering an ethics question with practical issues (cost, time) or the reverse.
• Saying covert observation is “unethical” and stopping; explain which ethical issue and how it might be addressed.
• Treating official statistics as either perfectly accurate or completely useless.
• Retelling a study’s findings when the question asks about its method.
