Market research: what the syllabus requires

· Market research = the collection, recording and analysis of information about customers, competitors and the market to support marketing decision-making.
· Businesses carry out market research to reduce uncertainty, identify customer needs/wants, improve product design, choose the right target market, support pricing/promotion/place decisions, and lower the risk of costly mistakes.
· In exams, always link research to a business objective such as higher sales, better positioning, reduced risk, or stronger customer satisfaction.
· How organizations carry out market research: define the problem, choose primary and/or secondary research, select a sample, collect data, analyse findings, and use the results to make decisions.

Primary market research

· Primary research = new/original data collected first-hand for a specific purpose.
· Main advantage: usually more relevant, up to date, and tailored to the business question.
· Main limitation: often more time-consuming, costly, and may have sampling bias or response bias.

Surveys

· Surveys collect data from many people using questionnaires or forms.
· Best for gathering quantitative data quickly from a relatively large sample.
· Useful for measuring preferences, satisfaction, awareness, and buying intentions.
· Strengths: can be cheap, fast, and easier to summarise statistically.
· Weaknesses: answers may be superficial, affected by poor wording, non-response, or dishonest answers.
· Exam tip: strong surveys use clear questions, an appropriate sample, and avoid leading questions.

This diagram shows a typical survey rating scale used in questionnaires. It is useful for understanding how surveys turn opinions into quantitative data that can be counted and compared. In IB answers, use it when explaining why surveys are efficient for collecting large amounts of standardised data. Source

Interviews

· Interviews involve asking respondents questions face to face, by phone, or online.
· Best for deeper understanding of opinions, motives, and customer experiences.
· Usually produce richer qualitative data than surveys.
· Strengths: interviewer can ask follow-up questions and clarify meaning.
· Weaknesses: can be slow, expensive, and influenced by interviewer bias.
· Exam tip: interviews are especially useful when a business wants to know why customers behave in a certain way.

Focus groups

· Focus groups = small guided group discussions used to explore attitudes, feelings, and reactions to a product, service, brand, or idea.
· Best for generating qualitative insights and testing concepts, packaging, advertising, or new product ideas.
· Strengths: participants interact, so businesses can hear multiple viewpoints and unexpected ideas.
· Weaknesses: small groups may be unrepresentative; results can be affected by group pressure, dominant participants, or moderator bias.
· Exam tip: focus groups are strong for exploration, but weak for making precise claims about the whole market.

This framework illustrates how a focus group is organised around a moderator, prepared prompts, and participant discussion. It helps show why focus groups are mainly used to collect qualitative insights rather than numerical totals. In exams, use it to explain why businesses choose focus groups when they want deeper reactions to ideas or products. Source

Observations

· Observations involve watching how customers actually behave in real or controlled situations.
· Useful for studying shopping behaviour, store layout movement, queueing, or how people use a product.
· Strengths: may reveal actual behaviour rather than what people say they do.
· Weaknesses: observers may not know why people behave in that way; behaviour may change if people know they are being watched.
· Exam tip: observation is strong for behaviour-based evidence, but weak for understanding motives unless combined with another method.

This image is an example of an observation chart, showing how observed patterns can be recorded systematically over time. It helps students understand that observation research focuses on recorded behaviour, not just opinions. In business, the same logic applies when firms observe customer movement, reactions, or usage patterns. Source

Secondary market research

· Secondary research = using existing data that has already been collected by others or previously by the business.
· Main advantage: usually faster, cheaper, and easier to access than primary research.
· Main limitation: may be outdated, too general, or not perfectly matched to the business problem.

Methods/techniques of secondary market research

· Market analyses: reports on market size, market share, trends, and competitor performance. Useful for broad market overview.
· Academic journals: credible and detailed sources for theories, research findings, and consumer behaviour analysis; may be less practical for quick decisions.
· Government publications: data on population, income, employment, inflation, demographics, or industry statistics; often highly reliable.
· Media articles: useful for current news, competitor developments, and emerging consumer trends; reliability varies by source.
· Online content: includes websites, reviews, databases, social media, and online reports; fast and accessible, but quality must be checked carefully.
· Exam tip: when evaluating secondary research, comment on reliability, relevance, cost, and currency.

Qualitative vs quantitative research

· Qualitative research = non-numerical data about opinions, feelings, motives, and attitudes.
· Typical methods: interviews, focus groups, open-ended survey questions, some observations.
· Best for explaining why customers think or behave in certain ways.
· Limitation: harder to summarise objectively and may be based on smaller samples.
· Quantitative research = numerical data that can be counted, measured, and statistically analysed.
· Typical methods: surveys, rating scales, sales data, and structured observations.
· Best for answering how many, how much, or what proportion.
· Exam tip: the strongest responses often explain that businesses may use both types because they are complementary.

Sampling methods

· Sampling = selecting a subset of the population to represent the whole market.
· Good sampling improves representativeness; poor sampling creates bias and weak conclusions.

Quota sampling

· Quota sampling selects people to match certain characteristics, e.g. age, gender, or income group.
· Strength: ensures important groups are included.
· Weakness: still not fully random, so bias may remain.

Random sampling

· Random sampling means every member of the population has an equal chance of being selected.
· Strength: reduces selection bias and can improve representativeness.
· Weakness: may be harder and more expensive to organise in practice.

This diagram shows a population and a sample chosen randomly from it. It is useful for explaining why random sampling can reduce selection bias and make research findings more representative. In IB exam answers, connect this to stronger decision-making from better data. Source

Convenience sampling

· Convenience sampling selects whoever is easiest to reach, e.g. nearby shoppers or online followers.
· Strength: fast, cheap, and simple to carry out.
· Weakness: often highly biased and less representative of the target market.
· Exam tip: convenience sampling may be practical for a small business, but findings are usually less reliable for major decisions.

How to evaluate market research in exam answers

· Judge whether the method matches the research objective.
· Consider cost, speed, accuracy, depth of insight, and representativeness.
· Distinguish clearly between primary vs secondary and qualitative vs quantitative.
· Explain whether the sample is likely to be biased or representative.
· Always end with a supported judgement about which method is most suitable for that business and why.

Common exam-ready comparisons

· Primary research vs secondary research: specific and current vs cheap and quick.
· Qualitative vs quantitative: depth and reasons vs numbers and measurement.
· Random sampling vs convenience sampling: more representative vs easier and cheaper.
· Interviews/focus groups vs surveys: deeper insight vs larger-scale measurable data.
· Strong evaluation often depends on the business context: budget, time, size of market, and purpose of the research.
