DA0-002 Data Governance Practice Question
An analyst is creating a report to show the relationship between advertising spend and website traffic over the past 12 months. The data has a few outliers due to special promotional events. Which chart type should the analyst use to clearly show the trend while minimizing the impact of outliers?
⚠ Common exam trap
Many exam-takers choose a bar chart (Option B) thinking it clearly shows trends over time, but they overlook that bar charts treat each period as a separate category and do not inherently reduce outlier impact, whereas a scatter plot with a trend line explicitly models the relationship and dampens outlier effects.

Correct answer & explanation
✓
Scatter plot with a trend line
A scatter plot with a trend line (Option D) is the best choice because it plots each data point individually, allowing the analyst to see the overall relationship between advertising spend and website traffic while the trend line (often a linear regression line) smooths out the influence of outliers. This chart type minimizes the visual impact of extreme values by focusing on the central tendency and direction of the data, making it ideal for identifying trends over 12 months despite promotional event spikes.
