UCAT Data Tables: how to solve them
A data table question gives you a grid of numbers, row labels down the side and column headers across the top, and asks you to pull out values and combine them. It’s a Quantitative Reasoning question type, answered as single-best-answer with an on-screen calculator, and tables are the single most common QR stimulus. The skill it tests is reading the data accurately under time pressure, then applying a simple operation (a percentage, a ratio, an average) to the right cells.
What is a data table question?
You get a short framing sentence, then a table of numbers, then a set of questions that read from it. Each question is single-best-answer with five options, you have a basic on-screen calculator, and you’re working to roughly 43 seconds per question across the section.
The arithmetic in QR rarely goes beyond percentages, ratios and rates, all of it Year 10 maths, so the table almost never beats you on the calculation. It beats you on the read. And every table, whatever its shape, is built from the same handful of parts: get fluent at reading each one and most of the traps further down this page stop happening.
Tab through the parts of a table. Each one highlights where it lives, and what to check before you trust a number.
One sentence above the table tells you what it measures and in what unit. Read it first: it sets the scope (two stalls, four weeks), the unit (pounds), and flags anything unusual, like the bakery not opening in Week 1.
Tables come in a few shapes (a simple grid, a two-way frequency table, a tiered-rate table, a set of summary statistics), and the shape changes what you compute. But it never changes the discipline: find the exact cell the question names, then apply one operation to it. The worked example below uses the same table.
A worked example
Same table, one sub-question. Every wrong option is a number you can reach from the table by one specific slip, so pin the exact row and column, divide by the original, and the lookalikes fall away.
By what percentage did the Bakery stall’s takings change from Week 2 to Week 3?
Common mistakes
The wrong answers on a table set are almost never bad arithmetic: they’re a number you can see, reached by one wrong move. And most of these slips aren’t specific to tables. The same wrong-base or mean-vs-median error bites on bar charts and pie charts too, because the trap lives in the operation, not the picture. So these guides are shared across Quantitative Reasoning; each links to a short worked example.

A reliable method
Practising data tables
Data tables reward one repeatable habit: read the headers, pin the exact cell, then divide by the right base. The fastest progress comes from doing enough of them that the wrong-cell and wrong-base slips feel wrong on sight, before a tidy-looking number can talk you into it.

Common questions
Do I get a calculator?+
Yes. Quantitative Reasoning and Decision Making both give you a simple on-screen calculator; Verbal Reasoning and Situational Judgement do not. The calculator handles the arithmetic, so the work is reading the right values and choosing the right operation.
How are data table questions scored?+
As part of Quantitative Reasoning’s 300–900 scaled score, which contributes to your total cognitive score (900–2700). Each question is single-best-answer, marked right or wrong, with no penalty for a wrong guess, so never leave one blank.
Do I need to memorise formulas?+
No. The maths rarely goes beyond percentages, ratios, rates and simple averages, all of it around Year 10 level. What’s tested is reading the data accurately and fast, not recalling formulas.
What’s the most common mistake?+
Dividing by the wrong base on a percentage, almost always dividing by the new value instead of the original. It’s one careless cell away on every table, which is why a deliberate “change over original, share over whole” habit is worth drilling until it’s automatic.
