Study Skills and Information Interpretation
What you must understand
This domain tests how well you locate, interpret, and organise information from texts, tables, charts, and schedules. Key concepts: skimming for gist and scanning for detail, interpreting tables, bar and line graphs, and pie charts, reading axes, units, legends, and footnotes, recognising trends and outliers, and evaluating source reliability. You also need basic note-taking and summarisation skills.
Traps to watch
- Axis manipulation: a truncated y-axis can exaggerate small differences - check where the scale starts.
- Misreading legends: colours or line styles may map to categories you assume wrongly.
- Confusing absolute and relative values: the largest slice of a pie chart may still be a small number in absolute terms.
- Ignoring footnotes that qualify the data.
- Correlation as causation in trend descriptions.
- Unit mismatches between the question and the table (thousands vs units).
Rule of thumb and worked example
Before reading data, note the title, axes, units, and legend. Then locate the specific figure the question asks for rather than reading every number.
Example: A bar chart shows sales rising from 100 to 110 units, but the y-axis starts at 90, making the bar look twice as tall. The real increase is 10%, not 100%. Always compute the actual change from the labelled values, not from visual height.
For reliability, prefer primary, recent, and methodologically transparent sources.
