DA0-002 Visualization and Reporting Practice Question
A dashboard uses a heatmap to show sales density by hour and day of week. Users report that the color scale is confusing because some low values appear similar to high values. Which design change improves clarity?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Switch to a diverging color scale
Using a diverging color scale with a neutral midpoint improves differentiation between low, medium, and high values. A sequential scale may still cause confusion. Increasing color steps or using a single hue does not address the issue.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a sequential color scale with more contrast
Why it's wrong here
Sequential scale may not highlight low vs high as well as diverging.
- ✗
Increase the number of color steps
Why it's wrong here
More steps can still appear similar if the scale is sequential without a clear midpoint.
- ✓
Switch to a diverging color scale
Why this is correct
Diverging scale uses two contrasting colors from a midpoint, making differences more apparent.
- ✗
Change to a single hue gradient
Why it's wrong here
Single hue can be even harder to differentiate across the range.
