Why do businesses use market research?

  • Market research is the collection, compilation and analysis of information about a market

  • Effective market research helps a business

    • Reduce risk when launching new products or entering new markets

    • Identify and understand the future needs and wants of customers

    • Understand consumer behaviour 

    • Identify how much consumers are prepared to pay

    • Identify potential gaps in the market which can be exploited to increase sales

    • Identify competitors and gauge their potential strengths and weaknesses

  • With effective market research businesses are well-placed to make informed decisions about the most effective way to use their valuable resources and develop a suitable marketing mix

  • On-going market research helps businesses to update their marketing strategy in line with customers' changing needs and preferences

Primary market research

  • Primary market research is the process of gathering information directly from consumers in the target market 

    • This process gathers information that does not already exist and is specific to the needs of the business collecting it

  • Surveys, interviews and focus groups are common primary market research methods

    • These methods make use of questionnaires to organise research questions and responses

Primary market research methods include surveys, interviews, observation and focus groups

Primary market research methods

Surveys

  • A series of questions are posed to a defined number of people using a questionnaire

  • Surveys can be conducted face-to-face, online, by phone or by post

Advantages

Disadvantages

  • Can reach a wide audience quickly

  • Data is easy to compare and analyse

  • Responses may be rushed or dishonest

  • Limited opportunity for follow-up or clarification

Interviews

  • A formal meeting between a researcher and a customer using structured or semi-structured questions

  • Interviews allow detailed responses and observation of body language

Advantages

Disadvantages

  • In-depth and detailed responses

  • Can explore topics further through follow-up questions

  • Time-consuming and expensive

  • Results may be harder to compare due to open-ended answers

Observation

  • A market researcher watches consumer behaviour in real time, such as shopping patterns, product placement, or packaging influence

Advantages

Disadvantages

  • Shows actual behaviour rather than reported behaviour

  • Useful for identifying trends or problems

  • Cannot always understand reasons behind actions

  • Can be intrusive or affect natural behaviour

Focus groups

  • Small group discussions led by a specialist to gather detailed feedback from target customers on products, services, or marketing strategies

Advantages

Disadvantages

  • Provides deep insights and opinions

  • Can test ideas before wider launch

  • A small sample size may not represent wider market

  • Dominant voices may skew the discussion

Sampling

  • Primary market research is conducted with a small representative sample of the market as a whole

    • Market researchers use carefully designed sampling methods from which accurate conclusions can be drawn about likely customer preferences and behaviour

    • In general, the larger the sample size, the more likely it is that results of market research activities will reflect the market as a whole

Why is sampling useful?

  • It saves time and money

    • It is usually too expensive and time-consuming to collect data from every potential customer

    • Sampling allows the business to get useful information quickly and at a lower cost

  • It can provides reliable insights

    • If the sample is chosen carefully, it can represent the larger market

    • This means the business can still learn about customer preferences, buying habits, or opinions without needing to ask everyone

  • It helps a business make better decisions

    • Sampling allows a business to test ideas, such as new products or adverts, before launching on a larger scale

    • This helps reduce risk

  • It is useful for identifying trends

    • By asking a smaller group of people from different segments, a business can spot patterns in customer behaviour or preferences

Secondary market research

  • Secondary research involves the collection, compilation, and analysis of data that already exists

    • It helps businesses make informed decisions without carrying out their own primary market research

  • Businesses must weigh up the reliability of secondary market research and aspects such as cost, relevance and availability of data when making a decision on which secondary data to use

Secondary market research can be sources from competitor websites, government data, trade magazines and market reports

Sources of secondary market research

Competitor websites

  • Businesses can visit the websites of their competitors to gather useful information about their products, pricing, promotions, customer service and branding

Why are they useful?

  • Comparing prices and features

  • Identifying current marketing strategies

  • Understanding how competitors position themselves in the market

Government sources

  • Governments publish a wide range of free and reliable data, including statistics on population, employment, income, business activity and economic growth

Why are they useful?

  • Spotting demographic trends (e.g. ageing population)

  • Analysing the economic climate (e.g. inflation, interest rates)

  • Understanding changes in consumer spending or regional business conditions

Market reports

  • Market research companies, such as Mintel or Euromonitor, produce in-depth reports on industries, consumer trends and market performance

  • These are usually detailed and may be expensive to access

Why are they useful?

  • Assessing market size and growth

  • Understanding consumer behaviour and preferences

  • Identifying future opportunities or threats in a market

Trade magazines

  • Magazines focused on a specific industry, often published by trade associations or business groups

  • They include news, expert opinions and case studies

Why are they useful?

  • Staying up-to-date on trends, new products, and innovations

  • Monitoring competitor activity within the industry

  • Gaining insight into best practices and future developments

Evaluating secondary market research

Advantages

Disadvantages

  • Cost-effective

    • Secondary research is often cheaper than conducting primary research since the data already exists

  • Time-saving

    • Information can be accessed quickly without needing to collect new data

  • Wide range of data

    • It covers many topics and often has large sample sizes, offering valuable insights

  • It may be outdated

    • Information might not reflect current market trends or customer preferences

  • Lack of relevance

    • Data might not be specific enough for the business’s needs, so primary market research may also be needed

  • Unknown accuracy

    • The reliability of the data can be uncertain if the original source is unclear or biased

Examiner Tips and Tricks

Be careful not to confuse primary and secondary research – primary gathers new data (e.g. surveys), while secondary uses existing data (e.g. reports). Mixing these up is a common exam mistake

Factors influencing the accuracy of market research data

  • The reliability and accuracy of market research depends upon a large number of factors, including:

1. Question phrasing

  • How questions are phrased in questionnaires or other tools used to conduct surveys

    • Questions should be written in such a way that they do not encourage a predetermined response

2. Sample selection

  • How carefully the sample is selected

    • Including its size, types of respondent chosen and how closely these reflect the intended target market

3. Skills of interviewer

  • Who conducts the research including their experience, research skills and source (primary or secondary?)

  • Potential for bias when conducting research or analysing results

    • The research and its analysis should be as objective as possible

4. Time and place of research

  • When and where the research is conducted

    • Customer tastes, fashions, economic conditions and technology change, giving data a relatively short period of usefulness 

    • Customers in different geographic areas can have very different opinions
