NEW QUESTION # 131
Which aggregation is available without requiring a table calculation or calculated field?
- A. Percent of total
- B. Sample covariance
- C. Standard deviation
- D. Running total
Answer: C
Explanation:
Standard deviation is an aggregation that is available without requiring a table calculation or calculated field.
Standard deviation is a statistical measure that shows how much variation there is from the average value in a set of data. Standard deviation is one of the predefined aggregations in Tableau that can be applied to any measure by selecting it from the context menu of the measure or from the drop-down menu on the Marks card6 The other options are not aggregations that are available without requiring a table calculation or calculated field. Running total, sample covariance, and percent of total are all examples of table calculations, which are computations that are applied to the values in an entire table or partition of a table. Table calculations can be created by selecting them from the context menu of a measure or by using functions in a calculated field7

NEW QUESTION # 135
Using the dataset, plot a Map showing all the countries, filtered by Market to only include LATAM. Which country in the LATAM Market has the highest shipping delay (sum of total number of days between the order date and the ship date)?
- A. Mexico
- B. Brazil
- C. Peru
- D. Argentina
Answer: A
Explanation:
VERY IMPORTANT QUESTION FOR THE EXAM, PAY ATTENTION
1) To find the number of days between order date and shipping date, we will make use of a calculated field:
In the data pane, click on the dropdown arrow, and choose create calculated field.
Let's name this calculated field "ShippingDelay" (you can name it anything you want :) )
2) Use the DATEDIFF() function, and pass it the arguments as follows:
'day' depicts that we want to calculate the number of DAYS between the two dates. The first argument is 'start_date' which is the ORDER_DATE (day the order was placed), the second argument is 'end_date', which is the SHIP_DATE (date the order was shipped). So by subtracting as follows: SHIP_DATE - ORDER_DATE, we can find the delay in shipping.
Click OK.
3) You should now have a new measure as follows:
4) Phew! The hard part is done! Now let's filter by Market to include only LATAM:
5) Drag Country to the view, and the new calculated field 'ShippingDelay' to SIZE on the Marks Shelf as follows:
*You can also click on Show Text Labels to be sure that you're choosing the Largest value*
Clearly, Mexico has the highest Shipping Delay!
NEW QUESTION # 136
Which of the following are the options to export the data used to build the view / visualisations?
- A. MS Access Database
- B. PDF File

*Export data in the view to Microsoft Access or .csv*
Export the data that is used to generate the view as an Access database (Windows only) or .csv file (Mac only).
1) In Tableau Desktop, select Worksheet > Export > Data.
2) Select a location and type a name for your Access database or .csv file.
3) Click Save.
4) If you're on Windows, the Export Data to Access dialog box displays to give you the option to immediately use the new Access database and continue working in Access without interrupting your work flow.

Alternatively, you can use the drop-down menu associated with the field in the Data pane and select the "Rename" option. Both methods provide a quick and easy way to change the name of a field without affecting the underlying data structure. The "Format menu" and "Replace Reference" option do not apply to renaming fields.

NEW QUESTION # 140
Which of the following would you use to edit the Shape, colour, and Text of your visualisations?
- A. Filter Shelf
- B. Analytics Pane
- C. Marks Card
- D. Data Pane
Answer: C
Explanation:
The Marks Card allows us not only to edit the Shape, Text and Colour, but also to modify the Tooltip and the level of detail of the visualisation!
The Marks card is a key element for visual analysis in Tableau. As you drag fields to different properties in the Marks card, you add context and detail to the marks in the view.
You use the Marks card to set the mark type (see Change the Type of Mark in the View), and to encode your data with color, size, shape, text, and detail. To change the mark settings, see Control the Appearance of Marks in the View.
In this example, three different fields have been dragged to different properties in the Marks card. Segment is on Color, Region is on Shape, and Quantity is on Size.
After you add a field to the Marks card, you can click the icon next to the field to change the property it is using. You can also click the property buttons in the Marks card to change those settings.
Many properties can have multiple fields. For example, you can add multiple fields to Label, Detail, Tooltip, and Color. Size and Shape can only have one field at a time. For more details, see Control the Appearance of Marks in the View.

NEW QUESTION # 147
You have a dashboard that shows car rental statistics by city, including a field named Car Dropoff City in the view. A URL action in the dashboard uses https://en.wikipedia.org/wiki/<Car Dropoff City> as the URL target.
When you click Salt Lake City in the view, to where will the URL action direct you?
- A. https://en.wikipedia.org/wiki/<Salt-Lake-City>
- B. https://en.wikipedia.org/wiki/<Car Dropoff City>
- C. https://en.wikipedia.org/wiki/Salt.LakeXity
- D. https://en.wikipedia.org/wiki/Salt+Lake+City+Car+Dropoff+City
Answer: D
Explanation:
When you click Salt Lake City in the view, the URL action will direct you to https://en.wikipedia.org/wiki/Salt+Lake+City+Car+Dropoff+City. A URL action is a hyperlink that points to a web page or other web-based resource outside of Tableau. You can use URL actions to create an email or link to additional information about your data. To customize links based on your data, you can automatically enter field values as parameters in URLs3 In this case, the URL action uses https://en.wikipedia.org/wiki/<Car Dropoff City> as the URL target, where <Car Dropoff City> is a field value from the view. When you click Salt Lake City in the view, Tableau will replace <Car Dropoff City> with Salt Lake City in the URL target. However, since spaces are not allowed in URLs, Tableau will encode them as + signs instead. Therefore, the final URL will be https://en.wikipedia.org/wiki/Salt+Lake+City+Car+Dropoff+City3 The other options are not correct because they do not reflect how Tableau encodes field values in URL actions.
