Which practice is recommended to maintain accuracy when creating charts?

• A. Use accurate scales.
• B. Add decorative 3D effects.
• C. Use inconsistent units.
• D. Omit sources.

Answer: (A)

Using accurate scales is essential because the axes translate data into visual distance, and that translation must reflect the true relationships in the data. When scales are accurate and chosen appropriately—such as starting at a proper baseline, using consistent interval steps, and labeling units clearly—readers can compare values reliably, see real differences, and track trends without being misled. On the other hand, decorative 3D effects can distort perceived sizes, inconsistent units confuse interpretation, and omitting sources undermines credibility. Keeping scales accurate is the strongest guard against misinterpretation and supports honest data communication.
