IB Economics Paper 2 Data-Response Technique: What You Actually Need to Know

Paper 2 gives you an unseen extract with data (text, a table, sometimes a graph) built around one syllabus theme, then four questions worth 2, 4, 8 and 15 marks. You need diagram accuracy, definitions in context, and — critically — every point tied back to the extract's actual figures and wording, not generic theory.

Each of the four question parts has its own mark scheme: 2 marks for definitions, 4 for a short explain-with-diagram, 8 for an extended response using theory plus data, and 15 for the essay-style question demanding analysis, a diagram, and evaluation. Marks are awarded against specific criteria, not overall impression.

SL students sit Paper 2 for 1 hour 30 minutes answering one extract; HL students get 1 hour 45 minutes and must answer both extracts on the paper. That's roughly 45 minutes per extract for HL, so pacing across the four sub-questions matters as much as content knowledge.

Use a four-part structure: define the key term, explain the theory with a fully labelled diagram, apply it explicitly to two pieces of data from the extract, then evaluate — using a second viewpoint, a time-frame argument, or a stakeholder comparison. Examiners call this the 'define-explain-apply-evaluate' chain, and skipping the apply step is the single most common reason strong students lose marks.

Examiners expect explicit use of data in the 8-mark and 15-mark questions — usually two specific references per response, quoted or closely paraphrased with the exact figure or line number. Vague gestures like 'the data shows the economy is growing' without a number attached rarely earn the application marks.

You should be able to draw, label and shift: supply and demand, PPC, circular flow, AD/AS (Keynesian and monetarist versions), the Phillips curve, exchange rate diagrams, and market failure diagrams (externalities, public goods). Paper 2 rewards a diagram that's correctly labelled and directly linked to the extract's scenario, not just neatly drawn.

Calculations (like PED, XED, or a tax revenue figure) usually appear within the 4-mark part and demand you show working, state the formula, and interpret the number in words afterwards. A correct number with no interpretation typically only earns partial credit.

Each Paper 2 exam session is built around a single theme from the four IB Economics themes: Microeconomics, Macroeconomics, International economics, or Development economics. You won't be asked to cross-apply content from a different theme, but you do need full command of every topic within whichever theme comes up.

Paper 1 is essay-based, testing pure theory with no data provided — you build the whole argument yourself. Paper 2 is data-response, meaning the extract gives you real-world context and numbers you must integrate into every answer. Paper 2 rewards precise use of given evidence; Paper 1 rewards depth of unaided theoretical construction.

Paper 2 counts for 40% of the SL grade and roughly 20% of the HL grade, since HL students also sit an additional Paper 3 (quantitative techniques) that Paper 1 and 2 weightings adjust around. Both levels use the same question structure and mark allocation per extract.

HL Paper 2 isn't conceptually harder question-by-question — it's the same four-part structure per extract — but HL students answer two extracts instead of one in a longer sitting, which tests stamina and consistency across two different real-world contexts rather than deeper theory.

Neither paper should be neglected since they're weighted similarly, but Paper 2 is often where students lose marks through poor technique rather than poor knowledge — failing to reference the data explicitly. Targeted worksheet practice on data application tends to move grades faster than more theory revision alone.
