5 free sample questions from the Exploring and Analyzing Data domain, with answers and explanations. The full TDS-C01 bank has 51 questions across 4 domains. Questions are scenario-based and written from the official Tableau exam guide.
To bucket a continuous measure like Age into ranges (0–9, 10–19, …) for a histogram, which feature should the user create?
A Bin divides a continuous measure into equal-size ranges (bins), the basis of a histogram. A Group (B) combines dimension members, a Hierarchy (C) nests dimensions for drill-down, and a context filter (D) controls filter order.
A user wants to create a new field that computes Profit Ratio as SUM([Profit]) / SUM([Sales]). What Tableau feature should they use?
A calculated field lets you define new values with a formula like SUM([Profit])/SUM([Sales]). A data source filter (B) limits data, a dashboard action (C) adds interactivity, and a story point (D) is a presentation step.
A user wants to group several individual product categories into a single custom category (e.g., combine three into 'Other'). Which feature should they use?
A Group combines selected dimension members into a single higher-level member (e.g., merging categories into 'Other'). A Bin (B) buckets a measure into ranges, a set (C) is a custom subset, and a trend line (D) is an analytics overlay.
A user adds a trend line to a scatter plot. What does it show?
A trend line fits a statistical model (e.g., linear) to the marks, summarizing the direction/strength of the relationship. It's not the source query (B), a filter (C), or a legend (D).
Which chart type best shows the relationship (correlation) between two numeric measures?
A scatter plot places two measures on the X and Y axes to reveal correlation and clustering. A bar chart (B) compares categories, a line chart (C) shows trends over a continuous axis, and a crosstab (D) is a text table.
