DA0-002 Visualization and Reporting Practice Question
In Looker Studio, what is the difference between dimensions and metrics?
⚠ Common exam trap
A common mix-up: candidates confuse the general data types (numeric vs. string) with the semantic roles in Looker Studio, leading them to choose option C, but the exam expects you to know that dimensions are always used for grouping (categorical) and metrics for aggregation (numerical) in the context of this tool.

Correct answer & explanation
✓
Dimensions are categorical; metrics are numerical
In Looker Studio, dimensions are fields that contain categorical data (e.g., text, dates, or geographic names) used to group and segment data, while metrics are numerical fields (e.g., counts, sums, averages) that can be aggregated. Option D is correct because this distinction is fundamental to how Looker Studio processes and visualizes data: dimensions define the rows or categories in a chart, and metrics provide the quantitative values to be measured.
