Which practice is recommended when using units in Task 1 data descriptions?

• A. Include units with figures, keep the same unit throughout; avoid mixing units unless clearly a comparison.
• B. Omit units entirely to keep text concise.
• C. Use different units for different data points to show variety.
• D. Place all units in a separate legend.

Answer: (A)

Consistency and clarity in using units when describing Task 1 data is what this item focuses on. Attaching the unit to every figure makes the meaning immediate and prevents misreading—for example, a number without a unit could be interpreted as meters, feet, or another measure, leading to confusion. Keeping the same unit throughout for a given parameter lets readers compare values directly and reduces the risk of arithmetic or scale errors. If there is a deliberate need to use different units to highlight a comparison, it must be clearly explained so readers understand why the change exists and how to compare the figures. Placing units in a separate legend or omitting them altogether removes the link between each number and what it measures, making the data harder to interpret and undermining accuracy.
