Exploring and Analyzing Data: free practice questions

5 sample questions from our 15-question bank for this domain — answers and explanations included. These are the same scenario-based style as the real Tableau exam.

1. A user wants to compute each region's sales as a PERCENT OF TOTAL across all regions in the view. Which feature is designed for this?

  • A. A table calculation (Percent of Total)✓ Correct
  • B. A data source filter
  • C. A group
  • D. A bin
Explanation

A table calculation (like Percent of Total) computes values based on the data already in the view (e.g., each mark relative to the total). A data source filter (B) limits data, a group (C) combines members, and a bin (D) buckets a measure.

2. What is a Tableau HIERARCHY used for?

  • A. Nesting related dimensions (e.g., Country > State > City) so users can drill down and up in a view✓ Correct
  • B. Aggregating a measure
  • C. Filtering the data source
  • D. Changing the mark type
Explanation

A hierarchy nests related dimensions (Country > State > City; Year > Quarter > Month) enabling drill-down/up in views. It doesn't aggregate measures (B), filter the source (C), or change mark types (D).

3. Which chart type best shows the relationship (correlation) between two numeric measures?

  • A. A scatter plot✓ Correct
  • B. A bar chart
  • C. A line chart
  • D. A crosstab
Explanation

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.

4. How can a user SORT a bar chart so bars appear from largest to smallest by their measure?

  • A. Apply a descending sort on the measure (via the toolbar sort button or the field's sort options)✓ Correct
  • B. Change the data type
  • C. Create an extract
  • D. Add a URL action
Explanation

Sorting the dimension by the measure in descending order arranges bars from largest to smallest — done via the toolbar sort or the field's sort menu. Changing data type (B), extracting (C), and URL actions (D) don't sort the view.

5. A user adds a trend line to a scatter plot. What does it show?

  • A. A statistical model line summarizing the relationship/direction between the plotted measures✓ Correct
  • B. The exact source query
  • C. A filter on the data
  • D. The color legend
Explanation

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).
