What the GMAT Data Insights section covers

  • Table Analysis
  • Graphics Interpretation
  • Two-Part Analysis
  • Multi-Source Reasoning

Read the labels first

Check units, headings and totals before calculating. Many wrong answers come from reading the wrong row or column.

Use only what you need

Multi-source questions give more information than any one question needs; find the source that answers it.

Two parts, one scenario

In two-part analysis, both answers come from the same situation, and often one part helps you find the other.

Common mistakes

  • Comparing totals when the question asks about rates or shares.
  • Missing a condition hidden in a second source.
  • Reading a graph's trend instead of its exact values.

How to study this section

  • Practise percent change and weighted averages with the on-screen calculator.
  • After each set, note which source or column held the key fact.
