CompTIA Data+ (DA0-002)VisualizationMedium
A senior data analyst is reviewing a newly developed sales dashboard. The dashboard uses different color palettes for each region's sales charts (e.g., blue for North, green for South, red for East), and the titles for similar metrics vary across different tabs (e.g., 'Total Revenue' on one tab, 'Sales Sum' on another). While the individual charts are accurate, the analyst notes that users are struggling to quickly interpret information and switch between views. Which design principle is MOST likely being violated?
- AConsistency and Alignment
- BProximity
- CData-Ink Ratio
- DVisual Hierarchy
Show answer & explanationAnswer & explanation
Correct answer: A. Consistency and Alignment
Inconsistent use of color palettes for the same type of data and varying terminology for identical metrics directly violates the principle of consistency, making the dashboard difficult to navigate and interpret.
Why the other options are wrong
- B. Proximity relates to grouping related items together; while potentially a factor, inconsistency in elements themselves is a more fundamental violation.
- C. Data-ink ratio focuses on minimizing non-data ink, which is not the primary issue described.
- D. Visual hierarchy concerns the arrangement of elements to guide the eye to important information; while related, inconsistency is a more direct fit.
Consistency and Alignment
A design principle ensuring that similar visual elements (colors, fonts, labels, spacing) are treated in the same way across a visualization or dashboard, and that elements are neatly arranged.
- Reduces cognitive load for users.
- Improves readability and ease of understanding.
- Applies to colors, fonts, terminology, layout, and spacing.
