NEW QUESTION # 189
Which of the following are valid ways of Grouping Data?
- A. From the Dimensions Shelf
- B. From the Analytics Pane
- C. Using Marks in the view
- D. Using Labels in the View
Answer: A,C,D
Explanation:
**IMPORTANT QUESTION AND EXPLANATION, PLEASE READ**
3 ways to group data -
1) Marks
2) Labels
3) Dimensions shelf.
*IMPORTANT*
If we Group the data by selecting the marks, then they remain separate marks in the view and then have the same colour. Also, a new group is created in the Dimensions shelf. Example - Using the sample superstore dataset, first plot a bar chart showing sales for each sub-category:
Here, if we Select Phones, Chairs and Storage by selecting the MARKS (Bars), and then group them:
They remain seperate marks (BARS) but are grouped by the same colour.
Now, if we didn't do this, and rather grouped by selecting their Labels (Names):
Then they no longer remain separate Marks (bars) but are rather consolidated into a single Bar:
Finally, we can group directly from the Dimensions shelf as follows:
Now choose Phones, Chairs and Storage and Click Group:
You will now automatically have a new Dimension as follows:

To create a dual axis chart for the problem mentioned:
1) Drag Product Type to the column shelf, and Sales and Profit to the Row shelf:
2) Now, to focus on 2013, drag Date to the filter shelf and select only 2013:
3) Now, click on the Profit pill in the Rows Shelf, and select dual axis:
4) Now, in the marks shelf, choose Sales, and change the chart type to bar. Similarly, for Profit, change the chart type to Line.
Now the chart looks like this:
Now we change the Profit chart type to line:
5) Finally, we synchronise the axis as follows: Right click on the axis, and choose 'Synchronise axis'
And, our final view and answer is:
NEW QUESTION # 192
Which of the following is the correct way to calculate Profit Ratio in Tableau?
- A. Profit / Sales
- B. SUM(Profit) / SUM(Sales)
- C. SUM(Sales)/SUM(Profit)
- D. Sales / Profit
Answer: B
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 # 194
Which of the following is an example of a Date Part?
- A. March 2019
- B. September 2020
- C. Q4 2017
- D. November
Answer: D
Explanation:
All answers except November are examples of Date Values (continuous in nature).
See below:
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!

NEW QUESTION # 196
Creating a scatter plot requires a minimum of how many measures?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
We can use scatter plots to visualize relationships between numerical variables!
In Tableau, you create a scatter plot by placing at least one measure on the Columns shelf and at least one measure on the Rows shelf (Total 2 minimum). If these shelves contain both dimensions and measures, Tableau places the measures as the innermost fields, which means that measures are always to the right of any dimensions that you have also placed on these shelves. The word "innermost" in this case refers to the table structure.
( Simple Scatter Plot)
(Matrix of Scatter Plots)
A scatter plot can use several mark types. By default, Tableau uses the shape mark type. Depending on your data, you might want to use another mark type, such as a circle or a square. For more information, see Change the Type of Mark in the View.
To create a scatter plot, follow the steps below:

NEW QUESTION # 198
What are three benefits of using an extract as compared to a live connection to a data source? Choose three.
- A. A live connection to a data source can be slow due to network and user traffic, whereas a connection to an extract improves performance.
- B. A live connection to a data source provides the best performance for data connections.
- C. Extracts are stored in memory (RAM), resulting in faster query performance as compared with live data connections.
- D. Calculated fields perform better in workbooks connected to extracts than in workbooks with live connections to a data source.
- E. An extract reduces the amount of data stored on a client computer as compared to a live data connection.
Answer: A,C,D
Explanation:
There are three benefits of using an extract as compared to a live connection to a data source:
A live connection to a data source can be slow due to network and user traffic, whereas a connection to an extract improves performance. An extract is a snapshot of data that is stored locally on your computer or on Tableau Server. An extract can reduce the load on the data source and speed up queries.
Extracts are stored in memory (RAM), resulting in faster query performance as compared with live data connections. When you use an extract, Tableau loads the data into memory and optimizes it for analysis. This allows Tableau to perform calculations and aggregations faster than with live connections.
Calculated fields perform better in workbooks connected to extracts than in workbooks with live connections to a data source. Calculated fields are custom fields that you create using formulas or expressions. When you use an extract, Tableau can process calculated fields more efficiently than with live connections.
NEW QUESTION # 199
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:
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 # 200
What is the one most important thing you should do after creating a Dual-axis chart?
- A. Change the colours
- B. Synchronise the axis
- C. Hide the axis
- D. Edit the labels
Answer: B
Explanation:
After creating a dual axis chart, make sure to synchronise their axis since they both might not be having the same y-axis.
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, the Sales 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.

From the official documentation:
As seen above, we can either turn the animations for the entire workbook (upper red box), or only for the current sheet ( lower red box )
1) Simultaneous animations
The default simultaneous animations are faster and work well when showing value changes in simpler charts and dashboards.
2) Sequential animations
Sequential animations take more time but make complex changes clearer by presenting them step-by-step.
NEW QUESTION # 203
Which of the following is true about 'Incremental refresh' when creating Extracts in Tableau?
- A. It replaces all of the contents in the extract
- B. They can only be used with large datasets
- C. There is no difference, both are the same when using extracts. They are different when using live connections.
- D. It only adds rows that are new since the previous refresh.
Answer: D
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.
NEW QUESTION # 204

To create a dynamic set:
1) In the Data pane, right-click a dimension and select Create > Set.
2) In the Create Set dialog box, configure your set. You can configure your set using the following tabs:
General: Use the General tab to select one or more values that will be considered when computing the set.
You can alternatively select the Use all option to always consider all members even when new members are added or removed.
None of the other options exist, and therefore are incorrect answers.
