NEW QUESTION # 25
A data analyst needs to identify outliers from a given dataset. Which of the following visualizations is the best way to identify outliers?

Answer: A

Explanation:
This question falls under theVisualization and Reportingdomain, focusing on selecting the appropriate visualization to identify outliers in a dataset.
* Box plot (Option A): A box plot displays the distribution of data, including the median, quartiles, and outliers (data points beyond the whiskers), making it the best choice for identifying outliers.
* Scatter plot (Option B): A scatter plot shows relationships between two variables, and while outliers may be visible, it's not specifically designed for outlier detection.
* Gantt chart (Option C): Gantt charts are for project scheduling, not suitable for outlier identification.
* Waterfall chart (Option D): Waterfall charts show cumulative changes (e.g., financial contributions), not designed for outlier detection.
The DA0-002 Visualization and Reporting domain emphasizes "translating business requirements to form the appropriate visualization," and a box plot is the standard visualization for identifying outliers.
