DA0-002 Data Governance Practice Question
A data analyst needs to present the distribution of customer ages to a non-technical audience. Which type of chart would be most appropriate?
⚠ Common exam trap
A common mix-up: candidates confuse a histogram with a bar chart, thinking a bar chart can show distribution, but a bar chart is for categorical data, not continuous numeric data grouped into bins.

Correct answer & explanation
✓
Histogram
A histogram is the most appropriate chart for displaying the distribution of a single continuous variable, such as customer ages, to a non-technical audience. It groups ages into bins and shows the frequency of customers within each bin, making the shape, center, and spread of the distribution immediately visible. This aligns with the DA0-001 objective of selecting visualizations that clearly communicate data insights to stakeholders.
