The purpose and methods of market research: focus groups

The idea

A focus group is a small, guided discussion with selected participants, used as a primary market research method to explore opinions, needs and reactions. A business recruits people who match its target market, then a moderator asks open questions about a product, brand or idea. The discussion is usually recorded so responses can be analysed for themes. For example, a café testing a new lunch menu might run two groups of eight customers, asking what they think of the dishes and prices. Focus groups give rich qualitative detail and allow follow-up questions, but they are time-consuming, can be expensive, and results may be influenced by group dynamics or a small sample. They are assessed through your ability to explain how the method works, apply it to a business context, and evaluate its strengths and limitations.

What earns the marks

• Defines a focus group as a small group discussion used to collect qualitative primary research about opinions, needs or reactions.
• Explains that participants are selected to match the target market and a moderator guides the discussion using open questions.
• Describes how the discussion is recorded and analysed to identify themes, preferences or concerns.
• Applies the method to a business context, such as testing a new product, brand or price with potential customers.
• Evaluates strengths, including rich detail, follow-up questioning and insight into why customers feel a certain way.
• Evaluates limitations, including small sample size, time and cost, and possible bias from group dynamics or moderator influence.

Common mistakes and how to put them right

• Confusing a focus group with a questionnaire.

  Put it right: A questionnaire collects written or online answers from many respondents, while a focus group is a guided group discussion that produces detailed qualitative data.

• Assuming a focus group is representative of the whole market.

  Put it right: A small group cannot represent all customers, so results should be treated as indicative rather than statistically reliable.

• Ignoring the moderator's role.

  Put it right: Without a skilled moderator, one participant may dominate, or the discussion may drift, reducing the usefulness of the findings.

• Treating focus group data as quantitative.

  Put it right: Focus groups mainly produce qualitative opinions and themes, not numerical data that can be easily generalised.

Exam tips

• When applying focus groups to a case study, name the business and state exactly what it wants to find out, such as whether customers would pay a higher price for a new product.
• For evaluation questions, weigh both benefits and drawbacks before reaching a judgement; for example, rich detail may be more useful than a larger but shallow survey.
• Use business terminology accurately, such as primary research, qualitative data, target market, moderator and sample, to show understanding.
• If asked to recommend a research method, justify why a focus group is suitable for the specific context, or explain why another method might be better.
