Which statement accurately describes creating a group by selecting headers in a view?

1. A. A new group updates the aliases from the selected headers.
2. B. The grouped dimension is added to Color.
3. C. The grouped dimension replaces the original dimension field on Rows or Columns.
4. D. A newly created group only exists in the current view.

Correct Answer: C
When creating a group by selecting headers in a Tableau view, the newly created grouped dimension replaces the original dimension field on either the Rows or Columns shelf. This grouping action aggregates the selected headers into a single group, and this new group dimension is automatically placed in the view, replacing the original dimension. This functionality allows for more simplified and customized categorization within the data visualization, enhancing the ability to analyze and interpret data according to specific groupings.

Which two functionalities can you provide to consumers by adding a parameter to a visualization? Choose two.

1. A. Change fields in the visualization.
2. B. Download the underlying data as a CSV file.
3. C. Change the results of calculations in the visualization.
4. D. Create a new field in the data source.

Correct Answer: AC
In Tableau, parameters are dynamic values that can replace a constant in calculations, filters, and reference lines. If you have a parameter controlling a calculation, changing the parameter value can change the results of that calculation, thus impacting the visualization. Parameters can also be used to switch between different fields in the visualization; for example, allowing users to choose which measure or dimension to display.
