GMAT Table Analysis: Complete Strategy Guide

What Is Table Analysis?

Table Analysis questions, unique to the GMAT Data Insights section, present you with a sortable spreadsheet-style table and three binary statements. Your task is to evaluate each statement as True or False (or Yes/No, or Inferable/Not Inferable, depending on the specific question framing) based solely on the data in the table. All three statements must be answered correctly to receive credit — there is no partial score.

The table is interactive: you can sort any column in ascending or descending order at will. This sort function is not a convenience feature — it is the central tool around which the entire Table Analysis strategy is built. Students who do not use it systematically average 30–45 additional seconds per statement, which almost guarantees running over the 2-minute time target.

The Sort-First Strategy: Why Scanning Never Works

Manually scanning a 6–10 row table for patterns is slow and unreliable because the human eye does not efficiently compare values across unsorted rows. When a statement asks 'does column A increase as column B increases?', scanning an unsorted table requires tracking two values simultaneously across every row — a process that takes 30–60 seconds and is prone to missed outliers. Sorting column B first reduces the same task to a 10-second left-to-right glance at whether column A values are trending upward.

The 4-Step Process for Every Table Analysis Question

1. Orient (15 seconds). Before reading any statements, spend 15 seconds understanding the table structure. What does each column represent? What are the units? Are any columns ratios, percentages, or absolute values? This orientation eliminates unit-confusion errors on the statements that follow.
2. Read the statement precisely (5 seconds). Read only the first statement. Identify the key variable or comparison it requires. Underline or note the specific claim.
3. Sort the relevant column (5 seconds). Determine which column, sorted in which direction, will most efficiently reveal whether the statement is true. Sort it. For correlation statements, you may need to sort one column and observe another simultaneously.
4. Evaluate and record (10–15 seconds). Based on the sorted data, determine the answer. For conditional statements ('all rows where X is true also have Y'), scan all rows meeting condition X — not just the first few. Record your answer and move to the next statement. Re-sort as needed for each new statement.

Statement Types and the Right Sorting Approach for Each

GMAT Table Analysis statements cluster into five recurring types. Recognising the type from the statement's phrasing tells you immediately which column to sort.

Five Common Traps and How to Avoid Them

• Not re-sorting between statements. The table retains its sort order from the previous statement. If you sorted by Revenue for statement 1, the table is still sorted by Revenue when you read statement 2. Always actively ask whether a new sort is needed before evaluating the next statement.
• Testing only the first few rows of a conditional. When a statement says 'all rows where X is true also satisfy Y', you must check every row where X is true — not just the top two or three. The GMAT regularly places a single counterexample in the fourth or fifth row specifically to catch students who stop checking early.
• Confusing 'must be true' with 'could be true'. These have different logical standards. 'Must be true' requires support from the data for every possible case. 'Could be true' requires only that the data is consistent with the statement — it does not need to be proven. One counterexample kills 'must be true'. 'Could be true' is False only if the data explicitly contradicts it.
• Misreading units. If one column is in millions and another is in thousands, a comparison between them requires unit normalisation. Read column headers carefully during the orientation step.
• Over-relying on the calculator. The DI calculator is available but slow to reach for on straightforward comparisons. Use it for precise aggregate calculations (exact averages of many values) but not for visual-trend or ranking questions where sorting provides the answer directly.

Worked Example: Evaluating Three Statements Against Real Data

The table below presents regional sales data for five business units. Use the 4-step process to evaluate each of the three statements.

Evaluate these three statements as True or False:

1. 'The region with the highest revenue also has the highest market share.' → Sort Revenue descending: East ($11.2M) is #1. Sort Market Share descending: East (38%) is also #1. Both extremes belong to East. True.
2. 'Every region that grew year-over-year had a market share above 10%.' → Sort YoY Growth: positive regions are East (+18%), North (+12%), South (+3%), Central (+1%). Now check each region's market share: East 38% ✓, North 28% ✓, South 20% ✓, Central 1% ✗. Central grew but has only 1% market share. A single counterexample makes the universal statement False. (The trap: three of four positive-growth regions have above 10% market share — checking only East, North, and South would produce the wrong answer.)
3. 'The median revenue across all five regions is greater than $5M.' → Sort Revenue ascending: Central $0.4M, West $3.8M, South $5.9M, North $8.4M, East $11.2M. Five data points — median is the 3rd value = South at $5.9M. $5.9M > $5M. True.

Time Management for Table Analysis

Table Analysis questions should take approximately 2 minutes for all three statements combined — roughly 15 seconds on orientation and 35–40 seconds per statement. This is achievable if you use the sort function for every statement. Students who scan instead of sorting typically spend 70–90 seconds on statements that should take 35 seconds, often running over 3 minutes on a single question.

The most effective practice for Table Analysis uses a live interactive sortable interface rather than static table screenshots. The physical act of reaching for the sort column and executing it is a separate skill from the analytical judgment of which column to sort — and it degrades under exam pressure if it has not been practised. OpenPrep's Table Analysis questions use a fully interactive sortable table that mirrors the exact test interface, so the sort function is already muscle memory before test day.
