  1. In Tableau, which shelf controls the level of detail (granularity) of the view independently of visual encodings?

    Answer: Detail shelf in the Marks card

    The Detail shelf adds a dimension to the view's granularity without changing color, size, or shape encoding.

  2. What is the key difference between a FIXED LOD expression and an INCLUDE LOD expression in Tableau?

    Answer: FIXED ignores view filters (except context filters); INCLUDE adds dimensions to the view's level of detail

    FIXED computes at a specified granularity regardless of view dimensions, while INCLUDE adds extra dimensions to the existing view level.

  3. Which Tableau feature would you use to create a parameter-driven top-N filter without writing a calculated field?

    Answer: Top filter using a parameter in the Filter dialog

    The Top tab in the Filter dialog lets you use a parameter to dynamically set the N value for a top/bottom filter.

  4. What happens to a secondary data source field when you create a blend in Tableau and the link field has unmatched values?

    Answer: Unmatched rows in the secondary source are excluded; matched primary rows show asterisks (*) for secondary values

    In a blend, the secondary source is left-joined on the linking field, so unmatched secondary values display as asterisks.

  5. In a Tableau scatter plot, what is the effect of placing a dimension on the 'Detail' shelf?

    Answer: It increases granularity so each dimension member gets its own mark without visual differentiation

    Adding a dimension to Detail disaggregates marks to that level without encoding color, size, or shape.

  6. Which type of join should you use in Tableau when you want all records from both tables, including non-matching rows?

    Answer: Full Outer Join

    A Full Outer Join returns all rows from both tables, filling nulls where no match exists on either side.

  7. What does the 'Pages' shelf in Tableau enable?

    Answer: It creates an animated playback through dimension members like flipping through pages

    The Pages shelf sequences the view by a field, allowing you to step or auto-play through each member like an animation.
