Data Insights — Charts & Graphs for the GMAT Exam — UK candidates
10% of the GMAT test plan. Interpreting bar charts, line graphs, pie charts, and scatter plots within the GMAT Data Insights section to draw valid inferences. Calibrated for British candidates.
Most exam coaching covers the curriculum at the same depth across all topics. That misses the asymmetry of high-stakes testing: a few topics carry disproportionate weight on the score. Data Insights — Charts & Graphs sits at roughly 10% of the Graduate Management Admission Test content distribution — Data Insights replaced Integrated Reasoning as a full scored section in the GMAT Focus Edition. Chart questions require candidates to extract numerical values, identify trends, and evaluate whether a stated conclusion follows from the visual data. Errors here are usually perceptual — misreading axis scales or confusing absolute vs relative values. Pass rates for the GMAT are published annually by the awarding body and vary by cohort and locale. For UK candidates preparing for GMAT, the calibration of study to local context matters: UK candidates often take exams for both domestic licensure (NMC, GMC) and migration purposes. IELTS UKVI is a separate, higher-stakes track.
Common failure modes
These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.
- !Misreading a dual-axis chart by applying the wrong Y-axis scale to a data series
- !Confusing percentage change with absolute change when both are shown on the same chart
- !Drawing causal conclusions from a scatter plot that only shows correlation
Study tips
- 1Practice reading axis scales first — before looking at the question stem — to anchor your interpretation.
- 2Distinguish explicitly between absolute values and percentage values for every chart you practice.
- 3Drill the four most common chart types (bar, line, pie, scatter) with 5 questions each per session.
- 4In the UK, GMAT schedules and reschedules align with state holiday calendars and post-Brexit fee adjustments — confirm pricing on the awarding body's site before booking.

A bar chart shows Company A revenue at $50M in 2021 and $60M in 2022; Company B revenue at $80M in 2021 and $88M in 2022. Which company had the greater percentage revenue increase?
- ACompany A, because $10M increase > $8M increase
- BCompany B, because its absolute increase is smaller
- CCompany A, because 20% > 10%Correct
- DBoth companies had the same percentage increase
Why this answer?
Company A: ($60M − $50M) / $50M = 20%. Company B: ($88M − $80M) / $80M = 10%. Despite Company A having a smaller absolute increase, its percentage increase is double that of Company B.

A scatter plot of hours studied vs exam score shows a positive correlation. Which conclusion is best supported?
- AStudying more hours causes higher exam scores
- BStudents who study more tend to score higherCorrect
- CExam scores determine how long students study
- DThe relationship is one-to-one
Why this answer?
A scatter plot can show association (correlation) but cannot establish causation. "Tend to score higher" accurately describes the positive correlation without implying a causal direction.
