  You can see that the option in Green symbolizes our correct answer, i.e only a Month. In our case that month is November (the correct answer).

  All other options are combinations of a year with one other value (like a month, quarter, or day). So this is how by looking at an option you can know if its a date part or date value!

• Question 158:

  True or False: A sheet cannot be used within a story directly. Either sheets should be used within a dashboard, or a dashboard should be used within a story.

  A. rue
  B. False
  B. False

  ---

  Explanation/Reference:

  It is possible in Tableau to use a sheet within a story directly. Moreover, in Tableau, a story is a sequence of visualizations that work together to convey information. You can create stories to tell a data narrative, provide context, demonstrate how decisions relate to outcomes, or to simply make a compelling case. At the same time, a story is also a collection of sheets, arranged in a sequence. Each individual sheet in a story is called a story point.

• Question 159:

  What is this view referred to as in Tableau?

  

  A. Analytics Pane
  B. Window Pane
  C. Data Pane
  D. Dimensions and Measures
  C. Data Pane

  ---

  Explanation/Reference:

  Tableau displays data source connections and data fields for the workbook in the Data pane on the left side of the workspace.

  The Data pane includes:

  Dimension fields ?Fields that contain qualitative values (such as names, dates, or geographical data). You can use dimensions to categorize, segment, and reveal the details in your data. Dimensions affect the level of detail in the view.

  Examples of dimensions include dates, customer names, and customer segments. Measure fields ?Fields that contain numeric, quantitative values can be measured. You can apply calculations to them and aggregate them. When you drag a

  measure into the view, Tableau applies an aggregation to that measure (by default). Examples of measures:

  sales, profit, number of employees, temperature, frequency. For more information on what dimensions and measures are, see Dimensions and Measures, Blue and Green.

  Calculated fields If your underlying data doesn't include all of the fields you need to answer your questions, you can create new fields in Tableau using calculations and then save them as part of your data source. These fields are called

  calculated fields. For more information on calculated fields, see Create Custom Fields with Calculations. Sets

  Subsets of data that you define. Sets are custom fields based on existing dimensions and criteria that you specify. For more information, see Create Sets. Named sets from an MS Analysis Services server or from a Teradata OLAP connector

  also appear in Tableau in this area of the Data pane. You can interact with these named sets in the same way you interact with other custom sets in Tableau. Parameters Values that can be used as placeholders in formulas, or replace

  constant values in calculated fields and filters. For more information, see Create Parameters.

• Question 160:

  You can _______________ your data to combine two or more tables by appending values (rows) from one table to another

  A. join
  B. blend
  C. concatenate
  D. union
  D. union

  ---

  Explanation/Reference:

  You can union your data to combine two or more tables by appending values (rows) from one table to another. To union your data in Tableau data source, the tables must come from the same connection. For example, suppose you have the following customer purchase information stored in three tables, separated by month. The table names are "May2016," "June2016," and "July2016."

  

  A union of these tables creates the following single table that contains all rows from all tables.
