Interpreting and Analysing Market Research Data
Interpreting and analysing market research data is the skill of reading and calculating from data presented in tables, charts, graphs and surveys, such as percentages, trends and sample sizes, to draw valid conclusions and judge how reliable that data is before it is used to make a marketing decision.
Before you start
Make sure you're comfortable with these topics first:
Method
- Learn to read data accurately from a table, bar chart, pie chart or line graph before doing any calculation: identify the exact figures, units and time periods involved.
- Practise percentage calculations commonly used with research data: percentage of a total, calculated as part divided by whole multiplied by 100; percentage change, calculated as new minus old, divided by old, multiplied by 100; and market share.
- Practise identifying a trend across several data points, such as rising, falling or fluctuating, and describing it using the actual figures from the data, not just a vague description.
- Learn to judge the reliability of research data: check the sample size, since larger is generally more reliable; how the sample was chosen, since a random, representative sample is more reliable than a convenience sample; and how recent the data is.
- Learn to draw a conclusion or recommendation from data, explicitly linking the numbers to what they mean for the business's marketing decision, rather than restating the data alone.
- For 'analyse' questions, build a chain of reasoning: state the data pattern, explain what it suggests, then link this to a likely consequence or recommendation for the business.
Worked example
A questionnaire of 500 randomly selected customers found that 320 said they would buy a new flavour of crisps if it were launched. Calculate the percentage of respondents who said they would buy the new flavour, and state whether this survey result is likely to be reliable evidence for the business's launch decision, giving one reason.
- Calculate the percentage: 320 / 500 x 100 = 64%.
- State the result clearly: 64% of respondents said they would buy the new flavour.
- Consider the sample: 500 respondents is a reasonably large sample, and they were randomly selected, which reduces the risk of sampling bias.
- Because the sample is both reasonably large and randomly chosen, it is likely to be fairly representative of the wider target market's views.
- Conclusion: the data is likely to be reasonably reliable evidence to support a decision to launch the new flavour, though the business should still consider how the question was worded and whether stated intention always matches actual future buying behaviour.

Q1A survey of 200 people found 90 preferred Brand A. Calculate the percentage who preferred Brand A.Show answer
Answer: 90 / 200 x 100 = 45%.
Q2A business's sales rose from 60,000 pounds to 75,000 pounds. Calculate the percentage increase.Show answer
Answer: ((75,000 - 60,000) / 60,000) x 100 = 25%.
Q3Why is a larger sample size generally more reliable than a smaller one?Show answer
Answer: A larger sample is more likely to represent the range of views or behaviours in the wider target market, reducing the effect of any single unusual response.
Q4What is meant by a 'random sample'?Show answer
Answer: A sample in which every member of the target population has an equal chance of being selected, reducing the risk of bias.
Q5A pie chart shows a business's sales by region: North 20%, South 45%, East 15%, West 20%. Which region has the smallest share of sales?Show answer
Answer: East, with 15%.
Q6Why might data collected five years ago be less reliable for a current marketing decision than data collected this year?Show answer
Answer: Customer preferences, trends and the competitive market can change over time, so older data may no longer reflect current customer views or the current market.
Q7A line graph shows a product's sales rising steadily for three years then falling in year four. What might this pattern suggest about the product's position in the product life cycle?Show answer
Answer: It may be approaching or entering the decline stage, since a fall in sales after a period of growth is a characteristic sign of decline.
Exam-style questions

Analyse how a business could use the following market research finding to inform its marketing decisions: 'In a survey of 600 customers, 78% of respondents aged 18-24 said they discovered new products through social media, compared with 22% of respondents aged 55 and over.'

Bloom and Co, a small florist, ran a customer survey and found 85% of respondents said they would value a same-day online delivery option, but the survey only sampled 40 customers who happened to be in the shop on a single Saturday afternoon. The owner is planning to invest 8,000 pounds in setting up same-day delivery based on this finding alone. Evaluate whether Bloom and Co should rely on this survey to make its investment decision.
