Suggested answer: A, C, E

Explanation:

If you've created a data connection that you might want to use with other workbooks or share with colleagues, you can export (save) the data source to a file. You might want to do this also if you've added joined tables, default properties, or custom fields---such as groups, sets, calculated fields, and binned fields---to the Data pane.

In order to avoid any confusions, what should you do after creating a Dual-axis chart?

Hide the axis
Hide the axis
Change the colours
Change the colours
Synchronise the axis
Synchronise the axis
Edit the labels
Edit the labels
Suggested answer: C

Explanation:

After creating a dual axis chart, make sure to synchronise their axis since they both might not be having the same y-axis.

Tableau TDS-C01 image Question 153 explanation 76496 09232024004744000000

To align the two axes in a dual axes chart to use the same scale, right-click (control-click on Mac) the secondary axis, and select Synchronize Axis. This aligns the scale of the secondary axis to the scale of the primary axis.

In this example, theSales axis is the secondary axis and the Profit axis is the primary axis.

If you would like to change which axis is the primary, and which axis is the secondary, select the field on the Columns or Rows shelf that is the secondary, and drag it in front of the primary field on the shelf until you see an orange triangle appear.

In this example, you can select the SUM(Sales) field on the Rows shelf, and drag it in front of the SUM(Profit) field. The Sales axis is now the primary and the Profit axis is the secondary.

Which of the following are compelling reasons to use a Stacked Bar Chart?

To visualize parts of a whole
To visualize parts of a whole
To easily visualize trends over time
To easily visualize trends over time
To be able to visualize complex information with fewer bars / marks
To be able to visualize complex information with fewer bars / marks
To visualize each discrete category using a separate bar.
To visualize each discrete category using a separate bar.
Suggested answer: A, C

Explanation:

Stacked bar charts will usually have lesser number of bars compared to a normal bar chart:

Normal bar chart - 9 bars

Tableau TDS-C01 image Question 154 explanation 76497 09232024004744000000

Stacked Bar Chart - 3 bars

Tableau TDS-C01 image Question 154 explanation 76497 09232024004744000000

We can easily see a 'part-of-a-whole' methodology being used here as well - we are seeing the breakdown of Segments within each Category.

To easily visualize trends over time -This is the definition of a line chart.

To visualize each discrete category using a separate bar -This can be accomplished using a simple bar chart, why use a stacked one?

True or False: It is not possible to blend axes for multiple measures into a single axis

False
False
True
True
Suggested answer: A

Explanation:

We can very much blend multiple measures into a single axis. Such charts are called Combined-Axis / Blended-Axis charts. Follow along:

Measures can share a single axis so that all the marks are shown in a single pane. To blend multiple measures, drag one measure or axis and drop it onto an existing axis.

Tableau TDS-C01 image Question 155 explanation 76498 09232024004744000000

Instead of adding rows and columns to the view, when you blend measures there is a single row or column and all of the values for each measure is shown along one continuous axis. For example, the view below shows quarterly sales and profit on a shared axis.

Note:If you drag a measure on to the canvas and only see asingleruler indicator instead of the double ruler indicator shown below, Tableau createsdual axesinstead of a blended axis. For more information about how to create dual axes, seeCompare two measures using dual axes.

Suggested answer: A

Explanation:

When using a Percent difference, Tableau calculates what the percent change has occured as compared to the last data value.BUT, for the first data value, there is no previous value to compare it to. Hence, it appears as NULL.

It replaces all of the contents in the extract
It replaces all of the contents in the extract
They can only be used with large datasets
They can only be used with large datasets
Suggested answer: A

Explanation:

Extracts are saved subsets of data that you can use to improve performance or to take advantage of Tableau functionality not available or supported in your original data. When you create an extract of your data, you can reduce the total amount of data by using filters and configuring other limits. After you create an extract, you can refresh it with data from the original data.

When refreshing the data, you have the option to either do a full refresh, which replaces all of the contents in the extract, or you can do an incremental refresh, which only adds rows that are new since the previous refresh.

Loads your actual file into Tableau

Sorts the data in descending order
Sorts the data in descending order
Suggested answer: B

Explanation:

Before you can build a view and analyze your data, you must firstconnectTableau to your data. Tableau supports connecting to a wide variety of data, stored in a variety of places.

By default, when you connect a data source to Tableau, Tableau will create a live connection to the data.

Live connection refers to a data source that contains direct connection to underlying data, which provides real-time or near real-time data. With a live connection, Tableau makes queries directly against the database or other source, and returns the results of the query for use in a workbook. Users can create live connections and then share them on Tableau Server so that other Tableau users can use the same data using the same connection and filtering settings.
