- Data sufficiency
Subtopics 5
- 01Numbers and relationsNumber questions depend on the domain: integers, fractions and real numbers do not permit the same shortcuts.
- 02Orders of magnitudeOrder of magnitude describes approximate scale, often through powers of ten.
- 03Arithmetic and proportional reasoningA proportion compares two ratios. A percentage names a fraction of a specified base; an average compresses observations and may hide their…
- 04Charts graphs and tablesA chart encodes quantities through labels, scales and visual marks.
- 05Data sufficiencyData sufficiency asks whether supplied statements determine an answer, not necessarily what the numerical answer is.
