Tableau Practice Test 1

Question 1

You can utilize  _________________ to union files across folders and worksheets across workbooks while working with Excel, 
text file data, JSON file data, or.pdf file data. The search is restricted to the connection that has been selected.

Accepted Answer

Wildcard Search

Answer

Wildcard Search (or Wildcard Union) is a powerful feature in Tableau that allows users to combine multiple files or worksheets that share a common naming pattern from a specified folder or workbook into a single logical table. This is particularly useful for data sources like Excel, text files, JSON, or PDF, enabling efficient unioning of data without manually adding each individual file or sheet. The search is indeed restricted to the currently selected connection.

Question 2

In Tableau, what is a story point?

Accepted Answer

A single worksheet or dashboard

Answer

In Tableau, a story point is a single page within a 'story,' which is a feature designed to present data insights in a guided narrative format. Each story point can contain either a single worksheet or a single dashboard, along with text annotations to explain the insights being presented. It serves as a snapshot of a particular view or analysis.

Question 3

Is it able to discretize a Measure?

Accepted Answer

B) Yes

Answer

Yes, it is possible to discretize a Measure in Tableau. While measures are typically continuous and represented by green pills, you can convert them to discrete fields. This can be done by changing the field's data type to discrete or by creating bins from a continuous measure, which effectively categorizes the continuous data into discrete ranges.

Question 4

In Tableau, how do you make an axis bold?

Accepted Answer

By right clicking on the axis, choosing format, and then setting its font to bold.

Answer

To make an axis bold in Tableau, you typically right-click directly on the axis in your view. From the context menu that appears, you select 'Format,' which opens the Format pane. Within this pane, you can then navigate to the 'Font' section and set the desired font style, including bold, for the axis labels and title.

Question 5

Assume you have a bar graph. Which of the following happens when we group by labels in a view?

Accepted Answer

A new mark (bar) is created, which consolidates all members of the group.

Answer

When you group by labels (or marks) in a Tableau view, such as selecting multiple bars in a bar graph, Tableau consolidates the selected members into a single, new mark. This new mark (e.g., a single bar) represents the aggregated value of all the members within that group, effectively combining them visually in the chart. Additionally, a new group field is created in the Dimensions pane.
