This module covers how a business decides what it needs to find out, where the information comes from, how survey questions can mislead, why a sample may not represent the market, and how far a result can be trusted. In exam answers these ideas become judgement: a research result is only useful if you say what it shows, what it does not show and what the business should do next.
Business Studies 0450 and Business 0264 are separate Cambridge specifications for different exam years. Check the current Cambridge IGCSE Business syllabus page and the code on your own entry for the exact content points and wording, for example which sampling methods your specification names.
The reasoning habits taught here stay useful across both. Our Business learning guide shows where this module sits among the others.
What should you already know?
You should know why a business needs customers and what decisions its owner makes, which is covered in enterprise and business purpose. It helps to have seen how objectives shape choices, from objectives and stakeholders. The numbers here need only division and percentages.
An orienting example
Warung Cendol Pak Mat in Melaka wants to open a second stall near a college in Seremban. The owner is unsure whether enough students would buy a RM5 bowl each week.
Step 1, frame the question. “Among students at the college, what share would buy a RM5 cendol at least once a week?” It names a group, a product, a price and a measure.
Step 2, use secondary data. A college prospectus says there are 3,200 students. This costs nothing and sets the possible market.
Step 3, collect primary data. The owner asks 40 students outside the canteen. 26 say yes. Since 26 ÷ 40 = 0.65, that is 65% of those asked.
Step 4, judge the evidence. The sample is only 40 people, at one place and one lunchtime, and “would buy” is a stated intention. The result is encouraging but not a promise.
Step 5, give a recommendation. “The survey suggests interest. A one-week trial stall would show real buying before the owner signs a lease.”
Every step used a fact about the stall and the college. A list of research terms alone would not have reached a recommendation.
In which order should you study it?
- Frame a question that research can answer: the starting point, because the question decides everything that follows.
- Distinguish primary and secondary data: choose and justify where evidence comes from.
- Identify a biased survey item: make sure your own questions do not push the answer.
- Assess sample limitations: judge who was asked and how many replied.
- Use research evidence without treating opinion as a market fact: bring it together into a careful conclusion.
Then work through the mixed practice set. The ratios tool can help you check the percentages and shares that appear in survey results.
Which traps catch most students here?
- Writing “good research” with no reason. Say what makes it good in this case.
- Calling data primary because it was bought. Primary means collected first-hand for the question.
- Fixing one flaw and missing another in a survey item, such as wording that is neutral but still asks two things.
- Treating the sample result as true of the whole market. It describes only the people asked.
- Using “proves” for stated opinions. Intentions are not sales.
Each lesson shows one of these slips in full and then corrects it.
How should you use the practice set?
Write each answer on paper first, in full sentences, then open the worked answer. Compare your reasoning, not only your conclusion. A short answer that names a term, uses a case fact and states a limit is stronger than a long list.
When something is wrong, use the routing notes at the end of the practice set to return to the right lesson. A mistake log helps you spot which kind of slip keeps repeating.
If you want a teacher to check your applied paragraphs against the case, our online one-to-one Business tuition is built around that kind of feedback.
