Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Including 3D effects to make charts look more professional
Why it's wrong here
3D effects can distort data perception and reduce readability, so they are not a best practice.
- ✓
Using consistent color coding across charts
Why this is correct
Consistent color coding helps users quickly interpret charts and maintain visual coherence, which is a best practice.
- ✗
Adding detailed axis labels and titles to every chart
Why it's wrong here
While labels and titles are important, adding overly detailed labels to every chart can clutter the dashboard and reduce clarity. Best practice is to use concise, clear labels.
- ✓
Placing the most important metric at the top-left or most prominent position
Why this is correct
Placing the most important metric at the top-left or most prominent position follows the natural reading pattern and draws attention to key insights, which is a best practice.
- ✗
Using as many bright colors as possible to make the dashboard attractive
Why it's wrong here
Using many bright colors can cause visual fatigue and confusion, making the dashboard less effective. Best practice is to use a limited, harmonious color palette.
