Breaking down the question
The question has two linked parts. First, it asks you to identify and justify the "most suitable" research technique for studying consumer behaviour. Second, it stresses "social correlates" — the social factors such as class, gender, age, education, occupation and reference group that shape what and why people consume. The command word "explain" requires justification, not a mere naming of a method.
The examiner is testing whether you can match a research problem to an appropriate technique. Consumer behaviour is a large, patterned phenomenon spread across a population, and the phrase "social correlates" signals that relationships between variables — consumption on one side, social background on the other — are central. This points strongly towards the survey method, ideally supplemented by qualitative techniques. A good answer defends a primary choice while acknowledging the value of methodological triangulation.
A weak answer simply describes one method in the abstract. A strong answer argues why that method fits this particular subject, and shows awareness of its limits. Our research methods notes set out the toolkit you can draw on.
How to approach it
Open by clarifying what "consumer behaviour and its social correlates" involves as an object of study — patterned consumption choices and their association with social variables. State early that the survey method, built on structured interviews and questionnaires with a representative sample, is the most suitable primary technique, and give your reasons.
Then justify the choice: surveys allow large samples, generate quantitative data amenable to statistical correlation, and can measure the relationship between consumption patterns and social background variables. Bring in sampling, questionnaire design and the use of scales.
Next, strengthen the answer by arguing for triangulation: combine the survey with focus group discussions, in-depth interviews and observation to reach the meanings and motivations behind consumption, which a questionnaire alone cannot capture. Cite Bourdieu on taste as socially structured to show the theoretical stakes. Close by weighing the limits of surveys — social desirability bias, superficiality — and conclude that a survey-led mixed design best serves the problem.
Model answer
Consumer behaviour refers to the patterned ways in which individuals and households choose, purchase and use goods and services, together with the attitudes and motivations behind those choices. To study it sociologically is not merely to record what people buy but to relate consumption to its "social correlates" — the influence of social class, income, occupation, education, gender, age, family life cycle, religion and reference groups. The task, therefore, is to establish relationships between consumption as a variable and these social characteristics. This dual requirement — a large, patterned phenomenon plus the measurement of associations between variables — makes the survey method the most suitable primary research technique.
The survey method involves collecting standardised information from a sample of respondents through questionnaires and structured interviews. Its central advantage for this problem is scale and comparability. Because consumer behaviour is distributed across a whole population and varies systematically with social background, the researcher needs data from a large, representative sample rather than a handful of cases. Probability sampling — stratified sampling by income group or region, for instance — allows findings to be generalised to the wider population with a known margin of error. The structured questionnaire, using attitude scales such as the Likert scale to measure preferences and brand loyalty, yields quantitative data that can be tabulated and subjected to statistical analysis.
Above all, the survey permits the measurement of correlation, which is exactly what "social correlates" demands. By cross-tabulating consumption patterns against social variables, the researcher can test whether, say, expenditure on particular goods rises with education, or whether brand choice differs by gender or reference group. Pioneers of survey research such as Paul Lazarsfeld demonstrated how consumer and audience behaviour could be linked statistically to social position and interpersonal influence. Correlation coefficients and multivariate analysis allow the researcher to isolate the effect of each social factor and to identify which correlates matter most.
Yet consumption is not only behaviour to be counted; it is also meaning. People consume to express identity, signal status and belong to groups. Pierre Bourdieu argued that taste is socially structured, a marker of class distinction rather than mere individual preference. Such meanings — why a household buys what it buys, the aspirations and anxieties bound up with consumption — cannot be fully captured by a fixed questionnaire. For this reason the survey should be combined with qualitative techniques in a design of methodological triangulation. Focus group discussions reveal how consumers talk about brands and status among peers; in-depth unstructured interviews uncover motivations and life-histories of consumption; and observation, including of shopping and household use, records actual behaviour rather than reported behaviour.
A well-designed study would therefore be survey-led but mixed. An exploratory qualitative phase — a few focus groups and interviews — would generate hypotheses and refine the categories and wording of the questionnaire. The main survey would then measure the strength and direction of associations across a representative sample. A final qualitative phase could interpret and explain the statistical patterns the survey uncovers, giving the numbers social meaning.
The survey does carry limitations that the researcher must manage. Respondents may give socially desirable answers, over-reporting healthy or prestigious consumption and under-reporting the rest. Questionnaires can be superficial, missing the subtle, often unconscious drivers of purchasing. Recall of past consumption is unreliable, and rigid categories may impose the researcher's assumptions on respondents. These weaknesses are precisely why triangulation matters: qualitative methods compensate for the survey's superficiality, while the survey compensates for the small, unrepresentative samples of purely qualitative work.
In conclusion, because consumer behaviour is a widespread, patterned phenomenon whose study centres on relationships between consumption and social variables, the survey method is the most suitable primary technique, for it alone delivers representative, quantifiable data on social correlates. But since consumption is also meaningful action, the survey is best embedded in a triangulated design that adds qualitative depth. Such a combination secures both the generalisability the problem requires and the interpretive richness that consumption as social behaviour deserves.
Examiner's perspective
Examiners reward answers that connect method to the specific research problem rather than reciting a textbook account of surveys. The phrase "social correlates" is the hinge of the question: the strongest scripts recognise that it points to the measurement of relationships between variables and therefore to a survey capable of correlation and cross-tabulation. Naming sampling, questionnaire design, scales and statistical analysis shows technical command.
A first-class answer does not stop at advocacy of the survey. It defends the choice, then earns extra credit by arguing for triangulation — using focus groups, interviews and observation to reach the meanings behind consumption — and by weighing the survey's limitations honestly. Anchoring the discussion in a named theorist such as Lazarsfeld or Bourdieu signals that the candidate understands why consumption is a genuinely sociological object and not merely a marketing one. Balance, justification and awareness of limits distinguish the top band.
