GMAT section coverage

What the Free GMAT Data Insights Version Covers

Rotate across charts, tables, statistics, rates, probability, data sufficiency, multi-source reasoning, and decision analysis to build integrated Data Insights performance.

01 Data Interpretation FundamentalsBuild the core literacy needed across the entire Data Insights section by learning how to read values correctly, interpret units and time frames, classify variables, and avoid classic misreading traps.
  • Read quantities accurately by checking units, scale, currency, percentages, and index formats
  • Track time frames carefully, including daily versus monthly data, fiscal versus calendar periods, and rolling averages
  • Interpret categories and groupings such as region, segment, product line, or cohort without mixing them up
  • Distinguish absolute values from derived values, absolute change from percentage change, and point estimates from ranges
  • Recognise variable types including categorical, numerical, discrete, continuous, ordinal, and binary variables
  • Avoid common traps such as denominator confusion, percentage-point mistakes, axis misreads, and ignored footnotes

02 Graphs, Charts, and Visual Data AnalysisStrengthen the visual reasoning side of GMAT Data Insights by learning how to interpret charts quickly, compare trends accurately, and separate real signals from misleading presentation choices.
  • Work confidently with bar charts, line charts, area charts, pie charts, scatterplots, histograms, and boxplots
  • Read dual-axis visuals, non-zero baselines, logarithmic scales, and rebased index charts with care
  • Compare slopes, trend direction, volatility, inflection points, seasonality, and structural breaks
  • Identify which category or series is driving the overall movement in a visual display
  • Spot inconsistencies between charts and the accompanying text before selecting an answer
  • Rank options efficiently under time pressure without sacrificing accuracy
Start Section 2 Free →
03 Tables, Pivot-Style Data, and Multi-Dimensional ComparisonsPrepare for dense table-based tasks by learning how to scan structure fast, compare categories across multiple dimensions, and derive the metric that actually answers the question.
  • Read headers, subheaders, totals, subtotals, marginal totals, and subgroup totals accurately
  • Handle missing values, N/A entries, suppressed cells, and rounding notes without making invalid assumptions
  • Compare performance across time, product groups, regions, channels, or customer segments
  • Solve optimisation-style prompts such as best efficiency ratio, highest ROI, or lowest cost per unit
  • Work through multi-constraint selection questions that require two or three conditions to hold simultaneously
  • Compute weighted averages, contribution analysis, and rate measures from grouped table data
Start Section 3 Free →
04 Descriptive Statistics and Summary MeasuresUse practical statistics as decision tools by learning when to rely on the mean, median, spread measures, percentiles, and distribution shape in a business-style setting.
  • Interpret mean, median, and mode and know when one measure is more suitable than another
  • Understand how extreme values affect averages and when a skewed distribution makes the median more informative
  • Use range, interquartile range, variance, and standard deviation conceptually to assess spread and consistency
  • Interpret quartiles, deciles, and percentiles without falling into top-10-percent versus 10th-percentile traps
  • Recognise normal, left-skewed, and right-skewed distributions and what they imply for business decisions
  • Compare distributions across groups and recognise aggregate-versus-subgroup risks such as Simpson’s paradox
Start Section 4 Free →
05 Rates, Ratios, Proportions, and Percent ChangeDevelop the calculation engine that powers many DI questions by mastering ratios, shares, weighted measures, productivity metrics, and percent-change reasoning.
  • Distinguish part-to-part ratios from part-to-whole ratios and convert them into usable totals and shares
  • Calculate percent increase, percent decrease, growth factors, and simple compound-growth ideas
  • Separate percentage points from percent change when comparing rates or market shares
  • Use unit-rate logic for measures such as revenue per user, output per hour, cost per unit, or utilisation
  • Work with weighted average price, weighted success rate, and blended metrics across uneven group sizes
  • Interpret index numbers correctly when the base is set to 100 and translate index movement into relative change
Start Section 5 Free →
06 Probability, Risk, and Basic Inference for Decision-MakingHandle uncertainty more confidently by applying probability, expected value, risk interpretation, and break-even logic to practical decision scenarios.
  • Use simple probability, complements, and the difference between mutually exclusive and independent events
  • Work with conditional probability when the question gives information about one event and asks about another
  • Compare uncertain choices using expected profit, expected loss, and break-even probability thresholds
  • Read uncertainty bands and value ranges without confusing likely outcomes with guaranteed outcomes
  • Judge when variability matters more than a higher average outcome in a decision context
  • Apply these ideas to survey interpretation, quality control, reliability, and other real business settings
Start Section 6 Free →
07 Two-Variable Relationships: Correlation, Causation, and Regression IntuitionImprove causal discipline by learning how to interpret relationships between variables without jumping from association to unsupported conclusions.
  • Read positive, negative, and near-zero correlation correctly and separate strength from direction
  • Notice how outliers can create or distort an apparent relationship between variables
  • Apply the principle that correlation does not by itself establish causation
  • Watch for reverse causality and omitted third variables that can mislead interpretation
  • Use line-of-best-fit and regression-style intuition for prediction without overclaiming explanatory power
  • Recognise extrapolation risk when a chart or trend is extended beyond the observed range
Start Section 7 Free →
08 Data Sufficiency in Data InsightsTrain the logic of sufficiency rather than brute-force calculation by learning how to decide whether the given information is enough to answer the question.
  • Identify whether the question asks for an exact value, a yes-or-no result, or a comparison
  • Focus on the minimum information required instead of solving more than the problem demands
  • Work with common DI sufficiency topics such as ratios, rates, inequalities, overlapping sets, and weighted averages
  • Check whether the conditions lead to a unique answer or whether multiple solutions still remain possible
  • Split cases carefully when sign, integer status, or range restrictions could change the result
  • Avoid classic traps such as assuming typical values, treating at least as exactly, or missing alternative cases
Start Section 8 Free →
09 Multi-Source Reasoning and Information IntegrationBuild the section-specific integration skills needed for GMAT DI by combining information from multiple tabs, reconciling definitions, and choosing the statement best supported by the evidence.
  • Read two or three information panes efficiently, including text, mini charts, and tables
  • Extract only the facts that matter instead of carrying every detail into the decision
  • Align time periods, naming conventions, and category definitions across different sources
  • Check whether totals and subtotals remain consistent when data is presented in multiple places
  • Identify which claim is supported, contradicted, weakened, or strengthened by the evidence
  • Use integrated evidence to decide which policy or option fits the stated constraints best
Start Section 9 Free →
10 Strategic Judgment and Decision-Oriented Data ReasoningPrepare for the decision-making heart of Data Insights by learning how to weigh trade-offs, interpret KPIs, critique weak arguments, and recommend the most defensible course of action.
  • Evaluate trade-offs such as profit versus risk, speed versus cost, or growth versus sustainability
  • Interpret core business measures including revenue, margin, CAC, LTV, retention, churn, and funnel conversion metrics
  • Make choices under budget caps, minimum thresholds, resource limits, and multi-objective constraints
  • Detect flawed reasoning based on cherry-picked time windows, misleading averages, and ignored base rates
  • Choose the most defensible conclusion rather than the most dramatic or exciting one
  • Recognise when the evidence is still ambiguous and when a firm recommendation is not yet justified
