What is market research and why do it?
Market research is collecting and studying information about a market: customers, competitors and trends.
Why businesses do it:
- To find out what customers want and need.
- To reduce risk before launching a product or opening a shop.
- To learn about competitors (their prices, quality, strengths).
- To spot gaps in the market and new trends.
- To set the right price and choose how to promote and where to sell.
A market is where buyers and sellers meet. It can be mass (large, general) or niche (small, special group).
Primary (field) research
New, first-hand data collected for your own purpose.
- Questionnaire / survey: fixed questions, online, by phone or face to face.
- Interview: a longer one-to-one talk.
- Observation: watch and count what people do (traffic past a shop).
- Focus group: a small group discusses a product with a guide.
- Test marketing: sell in one small area first.
- Social media and website analytics, loyalty-card data.
Advantages: up to date, specific to your question, competitors do not have it. Disadvantages: costs time and money; results depend on good questions and a good sample.
Secondary (desk) research
Data that already exists, collected by someone else.
- Government statistics and census data
- Market research reports sold by specialist firms
- Newspapers, magazines, trade journals
- Competitors' websites and annual reports
- Internal company records (past sales)
Advantages: quick, cheap or free, often covers large populations. Disadvantages: may be out of date, not exactly about your question, and competitors can see it too.
Most businesses start with secondary research, then fill gaps with primary research.
Sampling and data quality
The population is everyone you are interested in. A sample is the smaller group you actually ask.
- Random: every person has an equal chance of being chosen.
- Stratified: split the population into groups (age, region) and sample each in its correct share.
- Quota: the researcher must interview a set number from each group.
- Convenience: ask whoever is easy to reach. Cheap but often biased.
A bigger sample is usually more reliable but costs more. Bias happens when the sample does not represent the population or when questions push people towards an answer (leading questions).
Quantitative vs qualitative
Quantitative: numbers, percentages, averages (e.g. 62% would buy). Qualitative: opinions, feelings, reasons (e.g. "too sweet"). Businesses use charts, averages and trends to analyse results; sometimes simple statistics like correlation or confidence intervals.
Using the results: segments, market maps and value proposition
Market segmentation: dividing customers into groups with similar needs, by age, gender, income, location, lifestyle or usage. A business then chooses a target market.
Market map (perceptual map): a chart with two features (e.g. price and quality). Brands are placed on it. An empty area can show a gap in the market. But a gap may exist because nobody wants that product, so check with more research.
Value proposition: a short statement of why customers should choose you: the problem you solve and what makes you different.
Research also estimates market size (how many buyers, how much they spend) and market share (your sales ÷ total market sales × 100).
Try it
Plan a tiny survey for a school snack stall. Write 5 clear, non-leading questions (for example: "How much would you pay for a samosa? under ₹10 / ₹10–20 / over ₹20"). Ask 5 classmates, then 20. Did the top answer change? Then use the 3D slider to see why bigger samples help.
Key formulas and definitions
- Market research: gathering and analysing data about customers, competitors and markets
- Primary (field) = new, first-hand; secondary (desk) = already exists
- Sample = small group chosen to represent the population
- Sampling: random, stratified, quota, convenience
- Quantitative = numbers (what); qualitative = opinions (why)
- Market share (%) = firm's sales ÷ total market sales × 100
- Market map: brands placed by two features; empty area = possible gap
Worked examples
1. A bakery wants to know whether to sell gluten-free bread. Suggest one primary and one secondary method.
Primary: a short survey of customers in the shop, or a free tasting to test reactions. Secondary: national health data or a market report on how many people buy gluten-free products.
2. In a survey of 200 people, 58 say they would buy a new juice. What percentage is that? Is it quantitative or qualitative?
58 ÷ 200 × 100 = 29%. It is quantitative data because it is a number.
3. Total smartphone sales in a town are 5,000 a month. Shop A sells 1,250. Find its market share and explain one limitation of using a convenience sample to plan its next model.
Market share = 1,250 ÷ 5,000 × 100 = 25%. A convenience sample (e.g. only people inside Shop A) is biased: they already like Shop A, so it may overstate demand and miss what other buyers want.
Common mistakes
- Mixing up primary and secondary: if you collected it yourself for this purpose, it is primary.
- Thinking a bigger sample always removes bias. A big but badly chosen sample is still biased.
- Writing leading questions like "Don't you love our tasty new drink?" They push people to agree.
- Assuming every gap on a market map is a good opportunity. There may be no demand there.
