What is this view referred to as in Tableau?

• A. Dimensions & Measures
• B. Data Pane
• C. Analytics Pane
• D. Window Pane

Answer: B

Explanation:
Explanation
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.

You have just created a histogram and now want to be able to change the size of bins dynamically. Using which of the following will easily satisfy your requirement?

• A. Groups
• B. Sets
• C. Parameters
• D. Calculation

Answer: C

Explanation:
Explanation
A parameter is a global placeholder value such as a number, date, or string that can replace a constant value in a calculation, filter, or reference line.
For example, you may create a calculated field that returns True if Sales is greater than $500,000 and otherwise returns False. You can replace the constant value of "500000" in the formula with a parameter.
Then, using the parameter control, you can dynamically change the threshold in your calculation.
For example -

NEW QUESTION 70
True or False: To concatenate fields, they must be of same data type

• A. True
• B. False

Answer: A

Explanation:
Explanation
Yes! To concatenate fields, they must be of same data type. However, there is a workaround which we can use
- Type casting. See below:

Here, State and City are Strings, but Postal Code? Nope. It's an Integer. So we can simply use the STR() function to convert it into a String, and hence the entire equation becomes valid!

• A. Union
• B. Data Joining
• C. Data segregation
• D. Data Blending

Answer: D

Explanation:
Explanation
Data blending is performed on a sheet-by-sheet basis and is established when a field from a second data source is used in the view. To create a blend in a workbook already connected to at least two data sources, bring a field from one data source to the sheet-it becomes the primary data source.
Switch to the other data source and use a field on the same sheet-it becomes a secondary data source. An orange linking icon will appear in the data pane, indicating which field(s) are being used to blend the data sources.

The remote field name let's us see what the name of the column is in the ORIGINAL Data source.

 

NEW QUESTION 76
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

Answer: B

Explanation:
Explanation
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.

NEW QUESTION 80
Which of the following is the correct way to calculate Profit Ratio in Tableau?

• A. SUM(Profit) / SUM(Sales)
• B. SUM(Sales)/SUM(Profit)
• C. Sales / Profit
• D. Profit / Sales

Answer: A

Explanation:
Explanation
THIS IS A VERY IMPORTANT QUESTION
Aggregation is an important concept to consider when creating calculated fields. A calculated field for SUM([Profit]) / SUM([Sales]) will give you a very different answer than [Profit] / [Sales], even though both formulas are valid.
If you do not provide the aggregation within the calculated field, Tableau will calculate the equation for every record ( row ) in your analysis, then aggregate the answers for all of the rows together when the calculated field is added to the view.
In simple terms, if specify the aggregation such as SUM, what Tableau will do is that it will first calculate the sum of the Profit column ( say x ), then calculate the sum of the Sales column ( say y ), and then simply apply x/y ---> This is what we expect! Perfect!
BUT, if you don't specify the aggregation, it will go to every single ROW, perform Profit / Sales, and then aggregate the answers calculated for each row. This is simply NOT what we wan't!
An example:

 

NEW QUESTION 81
Which of the following are the options to export the data used to build the view / visualisations?

• A. MS Access Database
• B. PDF File
• C. JSON format
• D. CSV file

Answer: A

Explanation:
Explanation
You can export the data in a Tableau data source, including all or part of the records from your original data.
Alternatively, you can export only the portion of data used to generate the view.
Since the question mentions the data used to build the view, we'll focus on that :
*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.

 

NEW QUESTION 82
Using the Time Series table, create a cross-tab showing sales for each Assortment broken down by Year and Quarter. In Q4 of October 2017, what was the Average sales amount for the Hardware assortment?

• A. 1,461
• B. 112,256
• C. 111,060
• D. 1,222

Answer: B

Explanation:
Explanation
If you chose 111,060 you were SO close to the correct answer but made a small mistake - you didn't change the aggregation to AVERAGE! This is one of the common mistakes many test takers make, so keep this in mind.
To reach the correct answer, follow the steps below:
1) Draw Assortment to the Column shelf, and drag Year to the Rows Shelf. Then Drill down further on Year to accomodate Quarters and Months as well!
Although this seems enough, DON'T FORGET to change the aggregation like in the next step, which will completely change the values!


* The correct answer as you can see is 1,461 - Sales for Harware Assortment in 2017 Q4, October
