How to Answer Data Response Questions in Cambridge AS Level Economics (9708)

The data response in Cambridge International AS Level Economics (9708) is not a reading-comprehension exercise with economics added afterwards. It tests whether you can extract the right evidence from written, numerical and diagrammatic material and then use economic knowledge, analysis and evaluation to answer a sequence of focused questions. In the current 2026-2028 syllabus, Paper 2 lasts two hours and is worth 60 marks. Section A is one compulsory 20-mark data response question with approximately six parts. Cambridge explicitly says candidates should use relevant information from the source material to support their answers and should show evaluation where appropriate. That makes the core skill simple to state, even if it takes practice to master: use the data as evidence, then do economics with it.

Know where Section A fits into Paper 2

Paper 2 has three sections. Section A is the 20-mark compulsory data response. Section B is a 20-mark microeconomics essay choice and Section C is a 20-mark macroeconomics essay choice. Because Section A carries one third of the paper, it deserves roughly one third of your attention, but do not turn that into a rigid minute-per-mark rule. Some short parts can be completed quickly while a 4- or 6-mark analytical part needs more development. The assessment objectives matter here too. Across Paper 2, Cambridge allocates approximately 33% to AO1 knowledge and understanding, 37% to AO2 analysis and 30% to AO3 evaluation. Section A therefore rewards much more than extracting a phrase from the source. Recent examiner guidance specifically notes that 4- and 6-mark data-response parts can require explained analysis and evaluation, and that knowledge only earns credit when it is relevant to the question and, where possible, to the source context.

Read the question before mining the source

A good first pass is question-led. Read the part question and underline the command word, the economic issue and any extra instruction such as using the data, comparing two countries or drawing a diagram. Then return to the source looking for the evidence that answers that exact task. This prevents you from copying attractive statistics that are on the right topic but do not answer the question. Cambridge examiner reports repeatedly flag this problem. In one 2024 data-response question, some candidates described what happened in every month of a table instead of identifying the overall trend across the period. The source contained plenty of numbers, but the task asked for the pattern. The lesson is to let the question decide which data matter.

Treat each command word as a different job

Identify usually needs a precise feature, reason or item. Calculate needs the correct formula or arithmetic, clear working and the requested answer. Explain needs a causal mechanism, not just a definition. Compare needs similarities or differences using both sides of the comparison. Consider or assess requires you to examine the argument and make a judgement rather than simply list effects. Do not write the same style of paragraph for every part. A 2-mark identification question does not need an essay. A 6-mark assessment question usually does. Before you begin, let the command word set the depth.

Use source evidence as the first link in an analytical chain

A useful response structure is evidence, concept, mechanism, consequence. Start with a relevant fact from the source. Name the economic idea that helps interpret it. Explain the chain of cause and effect. Then state the economic consequence in the context of the country, market or policy being discussed. For example, imagine the source says a currency depreciated by 12% while the country imports a large share of its energy. A weak answer says, “the currency fell by 12%, so inflation may rise.” A stronger answer explains that the depreciation raises the domestic-currency price of imported fuel and other inputs, which can increase firms’ production costs and shift short-run aggregate supply left, creating cost-push inflation. The source statistic now supports the economics rather than replacing it.

Do not copy a statistic without interpreting it

A number only earns value when you use it. If unemployment rises from 5% to 8%, explain whether that supports the claim in the question and why. If two countries have different inflation rates, distinguish them instead of writing as though both economies face the same conditions. The June 2024 examiner report specifically noted candidates who failed to distinguish between two countries even though the source required separate treatment. Choose the smallest set of data needed to prove the point. One well-selected comparison is often stronger than four numbers copied into a sentence with no interpretation.

For trend questions, describe the pattern rather than every observation

When a table or chart covers several dates, begin with the overall direction: rising, falling, fluctuating, narrowing, widening or relatively stable. Then mention a turning point or exception only if it matters. Avoid writing a list of every figure unless the question explicitly asks you to describe each stage. A good trend answer is selective. “The trade deficit narrowed overall, although it briefly widened in the middle of the period” communicates much more economics than a sentence for every month.

Show calculation working and interpret the result

Section A can require calculations. Write the relationship or formula, substitute the source values and show the arithmetic clearly. This is particularly important when a wrong final answer might still allow credit for a correct method. Keep percentage points, percentages, index numbers and rates distinct. If the next part asks you to explain or assess the calculated value, use it immediately. A real interest rate of -3% is not just a number; it means inflation exceeds the nominal interest rate, so the purchasing power of savings may fall. Cambridge’s 2024 report found that many candidates could not calculate real interest rates correctly, showing why basic numerical relationships need to be secure before exam day.

Use diagrams when they make the analysis clearer

Cambridge encourages clearly labelled diagrams where appropriate. A diagram is useful when the question involves a market shift, intervention, exchange-rate change, inflation, unemployment or another relationship that is easier to analyse graphically. It is not automatically useful just because you know how to draw it. Integrate the diagram into the prose. State what causes the curve to move, identify the direction of the shift and explain the new equilibrium or consequence. Examiner reports repeatedly criticise perfectly drawn diagrams that are never referred to in the answer. A diagram is part of the reasoning, not a separate decoration.

Explain the mechanism all the way through

A common mid-level answer identifies the correct factor but stops before the economic mechanism. In the 2024 examiner report, candidates could often identify reasons for a depreciation from the source but did not explain why those reasons reduced demand for the currency and therefore caused its value to fall. The missing marks were in the link. Train yourself to ask one more “why?” after each step. If interest rates fall, why could investment rise? Because borrowing becomes cheaper. Why does that affect aggregate demand? Because investment is one component of AD. What happens next depends on spare capacity, the shape of aggregate supply and the wider context. Each link turns knowledge into analysis.

Evaluation should grow from the source

When the question uses assess, consider, discuss or another evaluative command, do not attach a memorised evaluation sentence at the end. Use the source to identify the condition that changes the argument. A policy may be more effective if spare capacity is high, less effective if demand is interest-inelastic, slower if there are implementation lags, or more costly if it creates a conflict with another policy objective. Recent examiner reports repeatedly note that candidates identified relevant policies but did not evaluate their likely success. Evaluation becomes stronger when it compares the alternatives and explains why the source circumstances make one more convincing than another.

Make the judgement answer the exact question

A judgement is not “there are advantages and disadvantages.” Decide what follows from the analysis. If the question asks which policy is likely to be more effective, compare effectiveness. If it asks whether a depreciation will improve the balance of trade, judge that outcome. If it asks whether one country will be affected more than another, explain the difference. Keep the judgement proportional to the evidence. You can say a conclusion is likely, uncertain or dependent on a condition without pretending the source proves more than it does.

Original practice example

Imagine a short source about Country R. Inflation is 9%, the central bank interest rate is 6%, the currency has depreciated by 10% and imported food and energy make up a large share of household spending. The government is considering tighter monetary policy and temporary subsidies on basic food. A calculation question might ask for the real interest rate: 6% - 9% = -3%. An explanation question might ask how the currency depreciation could affect inflation: imported food, fuel and intermediate inputs become more expensive in domestic currency, raising firms’ costs and household prices. An assessment question might ask whether higher interest rates are the best response. You could analyse weaker consumption and investment as borrowing becomes more expensive, but evaluate the policy by noting that part of the inflation is imported cost pressure, so higher interest rates may reduce domestic demand without directly reversing the import-price shock. The subsidy could reduce measured food prices temporarily, but it carries a fiscal cost and does not remove the underlying exchange-rate pressure.

Common data-response mistakes

1. Copying a source statistic without explaining what it shows economically.
2. Describing every value in a table when the question asks for the overall trend.
3. Ignoring the command word and answering a slightly different question.
4. Using relevant theory but failing to connect it to the country, market or policy in the source.
5. Identifying a cause but not explaining the economic mechanism that produces the outcome.
6. Treating two countries or groups as identical when the source gives different conditions.
7. Drawing a diagram and never referring to it in the written analysis.
8. Giving a policy definition instead of explaining how the policy would affect the problem in the source.
9. Writing an evaluative phrase such as “it depends” without explaining what it depends on.
10. Giving a final judgement that summarises the answer instead of deciding the issue in the question.

A reliable Section A routine

1. Read the part question first and underline the command word, issue and any special instruction.
2. Locate only the source evidence that directly answers that part.
3. For numerical material, identify the pattern or calculate the required value before writing theory.
4. Add the relevant economic concept and explain the cause-and-effect mechanism fully.
5. Use one or two precise data references rather than copying the whole source.
6. Draw a clearly labelled diagram only when it helps the analysis, and refer to it in the prose.
7. If the question requires evaluation, identify the source condition that weakens, strengthens or changes the argument.
8. Compare alternatives where the question asks which effect or policy is more likely or more important.
9. Finish with a judgement that answers the exact wording rather than a generic conclusion.
10. Before moving on, check that every sentence is either source evidence, economics or a link between the two.

Put it into practice

Take one recent Economics (9708) Paper 2 Section A and complete only the 20-mark data response. After marking it, label each lost mark as source use, knowledge, analysis, calculation, diagram or evaluation. Then redo only the weak part before attempting another full paper. Inside NeuraGeek, you can use Economics (9708) past-paper and topical practice alongside the existing 20-mark essay guide, treating Section A data response and Sections B/C essays as separate exam skills that need different forms of practice.
