Question 237 of 986
DA0-002 Data Governance Practice Question
A data analyst creates a dashboard that includes a map showing sales by region. The map uses a continuous color gradient from light yellow to dark blue. Some regions with very high sales appear as dark blue, but many regions with moderate sales appear similar. Which improvement would most enhance the readability?
⚠ Common exam trap
Many candidates think a diverging color scheme (Option A) is always better for readability, but CompTIA often tests the distinction between continuous vs. discrete scales—the core issue is that a continuous gradient causes perceptual blending in the mid-range, which only a discrete scale with distinct bins can resolve.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a discrete color scale with distinct bins for sales ranges.
A discrete color scale with distinct bins for sales ranges eliminates the ambiguity caused by a continuous gradient, where moderate sales values blend together. By grouping sales into defined intervals (e.g., $0–$10K, $10K–$50K, etc.), each region is assigned a unique, easily distinguishable color, making it immediately clear which sales bracket a region falls into without requiring precise color differentiation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Switch to a diverging color scheme with a neutral midpoint.
Why it's wrong here
A diverging scheme is useful when data has a meaningful midpoint, but may not solve the issue of similar colors for moderate values.
- ✗
Increase the map size to show more detail.
Why it's wrong here
Increasing size does not improve color discrimination.
- ✗
Add data labels to each region showing exact sales numbers.
Why it's wrong here
Data labels add clutter and do not address the core issue of color differentiation.
- ✓
Use a discrete color scale with distinct bins for sales ranges.
Why this is correct
Discrete bins with distinct colors make it easier to differentiate between ranges, reducing visual ambiguity.
