3.1.1 Role of marketing

Job One-line meaning Typical action
Identify customer needs Find out what customers want Surveys, studying sales records
Satisfy customer needs Supply the right product, price, place, promotion Adjusting features and service
Maintain customer loyalty Keep customers buying again Points schemes, consistent quality
Build customer relationships Two-way contact over time Feedback requests, personal offers

Distinction: loyalty is the repeat buying; a relationship is the contact that encourages it.

A four-box cycle for Ambergate Cycles: identify needs (buyers ask for mudguards and lights), satisfy needs (both fitted as standard), build relationships (text offer after six weeks, reply recorded) and maintain loyalty (buyers return and buy accessories). Loyalty is repeat buying; a relationship is the contact that encourages it.
Each action at Ambergate Cycles ties to one of the four jobs of marketing.

3.1.2 Market changes

  • Why spending patterns change: incomes, tastes and fashion, population, technology, prices of related goods, health and environmental attitudes.
  • Why changing needs matter: products that no longer match needs lose sales, leave unsold stock and hand customers to rivals.
  • Why markets become more competitive: easier entry for new firms, online selling, global rivals, price comparison websites, better-informed customers.
  • Responses: more research, new or adapted products, price changes, better service or quality, stronger promotion, new customer groups, lower costs.

Method in steps for a “respond to change” question

  1. Name the change in the case.
  2. Say what it does to the business (sales, costs, share of customers).
  3. Choose a response that fits that business.
  4. Explain why it helps, and note a drawback or cost.
Fresh milk sales fell 22.9% between 2021 and 2025 while the new plant-based range lifted the total to a fall of only 3.2%. The bars show the three years in the lesson table, split into fresh milk and plant-based.
A market shift shows up in one product but may be offset by a new range.
Six causes point at a central box, spending on a product, which can rise or fall: incomes, tastes and fashion, population, new technology, prices of rival or complement goods, and health, environmental or social attitudes.
Six causes can push spending on a product up or down.
Three columns: no rivals (one shop, little pressure to improve), a few rivals (three shops, some pressure on price) and many rivals (six shops, strong pressure on price and quality), shown with one, two and three filled bars.
The more rivals a business has, the more pressure it faces to compete.
A shop selling only to a few nearby customers inside a small dashed circle, then the same shop with a website reaching many customers spread widely. Labels say e-commerce affects marketing (wider markets) and operations (order fulfilment).
E-commerce lets a business reach customers well beyond its local area.

3.1.3 Niche and mass marketing

Niche Mass
Market Small, specific Large, general
Benefits Fewer rivals; higher price possible; loyal customers High volumes; lower unit costs; spread of risk
Limitations Small sales; risk if tastes change; larger rivals may enter More rivals; price competition; promotion is costly; does not suit everyone exactly

Distinction: the question is never “which is best” but “which suits this business”.

Two panels show the same market of twelve people. Mass marketing aims one offer at all twelve (benefit: economies of scale; limitation: more rivals). Niche marketing aims a tailored offer at three of them (benefits: premium prices, less competition; limitation: fewer buyers).
Mass marketing targets everyone with one offer; niche marketing targets a small segment.

3.1.4 Market segmentation

  • Definition: dividing a market into groups of customers with similar characteristics or needs.
  • Syllabus examples: age, socio-economic grouping, location, gender.
  • Benefits: products, prices and promotion aimed at each group; less wasted spending; gaps in the market found; higher sales and loyalty possible.

Method in steps for “recommend and justify a method”

  1. Look for the characteristic that clearly changes what people buy in the case.
  2. Recommend it.
  3. Give the evidence (a figure or detail from the case).
  4. Explain how the business will use it.
  5. Say why another method is weaker, or what could limit the recommendation.
The 25 to 44 group is 43% of customers but 55.2% of the 35,860 dollar revenue. Other groups earn a smaller share of revenue than of customers except 45 to 64, which is level at about 30%. This is why age is a useful basis for segmenting.
Age is a sensible segmentation basis because the 25 to 44 group earns 55.2% of revenue from 43% of customers.
Four cards show a market split by age, location, gender and socio-economic group. Each group of people is a segment. Each segment can be given its own promotion and products.
A market can be segmented by age, location, gender or socio-economic group.

3.2.1 Market research

Uses to a market-orientated business: identify needs, estimate demand and market size, choose features, prices and promotion, study rivals, reduce the risk of failure.

Primary Secondary
Meaning New data collected first-hand Existing data collected by others
Benefits Specific, up to date, private to the business Cheaper, quicker, plenty available
Limitations Slow, costly, can be biased May be out of date or not specific; rivals can use it
Primary method Strength Weakness
Postal questionnaire Wide reach Slow, few replies
Online survey Fast and cheap Only reaches online respondents
Interviews Detailed answers Time-consuming, interviewer influence
Focus groups Reveals attitudes Small group, dominant voices

Secondary methods: online research, government sources, paying for commercial market research reports.

Sampling: asking everyone is too slow and expensive, so a sample represents the whole market. Bigger and more representative means more reliable.

Accuracy depends on: sample size and representativeness; clear, non-leading questions; honest, unbiased researchers and respondents; recent data from a reliable source; enough people responding.

Two grids of 20 people. A representative sample of 10 has 7 online and 3 not online, matching the market at 70 percent online. An email-only sample of 10 is 100 percent online and overstates online interest. Hobsworth emailed 300 and 240 replied, 80 percent.
A representative sample mirrors the market; a biased one gives misleading results.
Primary research (postal questionnaire, online survey, interview, focus group) is collected by you: costlier and slower but fits your question. Secondary research (online sources, government statistics, paid reports) already exists: cheaper and quicker but not made for you. A sample of a few people stands for the whole target market.
Primary research is collected first-hand, secondary research already exists, and a sample stands for the whole market.

3.2.2 Using results

  • Read title, labels, units and scale first.
  • Look for the largest, the smallest and the change over time.
  • Percentage = part ÷ total × 100.
  • Pie chart angle = (number ÷ total) × 360 degrees (the standard form).
  • State a simple conclusion that answers the business question, and one limit on it.

Small reminder. If 45 of 150 respondents choose option B, that is 30%, and its pie angle is 108 degrees.

The pie shows in store 40% (144 degrees), website 45% (162), phone 5% (18) and market stall 10% (36). Each angle is number divided by total times 360 and the angles add to 360.
Pie angle = (number / total) x 360 degrees, shown on the lesson's Hobsworth data.

Applying the ideas: short reminders

Customer needs. A shop that notices parents asking for sugar-free snacks is identifying a need. Stocking them satisfies it. Remembering a regular customer’s usual order builds a relationship.

Changing market. If a rival opens an online store and your sales fall, say what changed (competition), what it does (lost customers and revenue) and what the business could do (match delivery speed, add a loyalty scheme), then judge whether that response suits a business of its size.

Niche against mass in one line each. A bakery selling only vegan celebration cakes is niche: loyal buyers, but few of them. A factory producing millions of identical plastic cups is mass: low unit cost, but buyers switch on price.

Choosing a research method. Match the method to the question and the budget:

  • need deep opinions on a new design: focus group or interviews
  • need views from many people across a country: online survey or postal questionnaire
  • need background on the size of a market quickly: secondary sources, such as government statistics
  • need very detailed industry figures and can afford them: a commercial report.

Reading a chart. For each chart, write one sentence of fact (“45% chose the website”), one of meaning (“nearly half the sample would use it”) and one of caution (“only 240 people answered”).

Exam technique for this topic

  • Check the command word. State or identify needs a short answer. Explain needs a point plus a reason. Analyse needs a chain of consequences. Evaluate, justify and recommend need both sides and a reasoned judgement.
  • Use the name of the business and one detail from the case in each developed answer.
  • In a calculation, show the working line and finish with a unit or percentage sign.
  • Keep one idea per paragraph so that each point is easy to see.

Must-know distinctions

  • Needs (what customers want) against wants for a specific brand: research finds both.
  • Niche (small, specialist market) against mass (large, general market).
  • Primary against secondary research.
  • Sample (the group asked) against population (everyone in the target market).
  • Segmentation (dividing the market) against niche marketing (choosing to serve one small part).

Quick self-test

  1. List the four jobs of marketing set out in the syllabus.
  2. Explain the difference between customer loyalty and customer relationships.
  3. Give two reasons why customer spending patterns may change.
  4. State one limitation of niche marketing and one of mass marketing.
  5. Name the four bases of segmentation given as examples.
  6. Distinguish primary research from secondary research.
  7. A firm has 2,400 customers and surveys 150 of them. What percentage is surveyed?
  8. In a pie chart, 54 out of 180 respondents chose “café”. What angle shows them?
  9. Name two methods of primary research and one of secondary research.
  10. A survey finds that 36 of 120 people would buy a new flavour. What is the percentage?
  11. Give two factors that reduce the accuracy of research data.
  12. Why might a bar chart of last year’s results be unreliable for a decision today?

Answers

  1. Identify customer needs, satisfy customer needs, maintain customer loyalty, build customer relationships.
  2. Loyalty is customers choosing to buy again; relationships are the contact (feedback, personal offers) that encourages this.
  3. Any two: change in income, tastes, population, technology, related prices, attitudes.
  4. Niche: small market limits sales or growth. Mass: strong competition, often on price.
  5. Age, socio-economic grouping, location, gender.
  6. Primary is first-hand data collected for the purpose; secondary already exists, collected by someone else.
  7. 150 ÷ 2,400 × 100 = 6.25%.
  8. 54 ÷ 180 × 360 = 108 degrees.
  9. Primary: any two of postal questionnaire, online survey, interviews, focus groups. Secondary: online, government sources or paid commercial reports.
  10. 36 ÷ 120 × 100 = 30%.
  11. Any two: small or unrepresentative sample; leading questions; biased or dishonest answers; out-of-date secondary data; low response.
  12. Tastes, prices or competitors may have changed since it was collected, so the data may be out of date.

Where marks are usually lost

  • Listing the four jobs of marketing without applying any to the business in the case.
  • Writing that niche marketing “has no competition”, which is rarely true.
  • Recommending a segmentation method with no evidence from the case.
  • Describing a research method but not saying why it suits this business.
  • Saying “primary research is better” without weighing cost and time against accuracy.
  • Describing a large sample as accurate even though it asked the wrong people.
  • Calculating a percentage or angle correctly but writing no unit or working.
  • Describing a chart (“it goes up”) without a conclusion for the business.
  • Giving the same point twice in different words in a “two” question.

Frequently asked questions

What is the difference between niche and mass marketing? Mass marketing sells one product to a large, wide market with little variation. Niche marketing sells a specialist product to a small, specific part of a market.

Is a large sample always accurate? No. A large sample can still be biased if the wrong people are asked, so it must also be representative of the target market and use clear, non-leading questions.

What are the ways of segmenting a market in Cambridge O Level Business 7115? The syllabus examples are age, socio-economic grouping, location and gender. Choose the basis that best explains differences in buying behaviour in the case.

What is the difference between customer loyalty and customer relationships? Loyalty is the behaviour of repeat buying. A relationship is the two-way contact, such as asking for feedback or remembering regular buyers, that encourages it.
