When you’ll see it

A table, pie chart, bar graph or paragraph of data with several questions on it.

How this chapter is tested

52 questions, falling from 2.6 to 1.7 a paper, and only one HARD question in the whole chapter. Every question is arithmetic on data you are given.

Questions come in sets on one table or chart, so reading it carefully once pays for several answers.

The sub-skills

The distinct skills inside the chapter, in the order to learn them.

  • Tables

    Percentages and changes between rows or columns.

  • Pie charts

    Angle ÷ 360 is the share; compare charts only through actual counts.

  • Bar and line graphs

    Read values, then compare year on year.

  • Caselets

    Build the table from the paragraph first.

Traps to expect

Distractor shapes this chapter reuses. The Traps page covers the ones that cut across chapters.

  • Comparing shares across charts

    25% of one total and 25% of another are different counts.

  • Percentage change base

    Change is measured against the earlier value.
