NEW QUESTION # 146
True or False: Trend lines can only be used with numeric or date fields

A. True
B. False

Answer: B

Explanation:
Explanation
You can show trend lines in a visualization to highlight trends in your data.
To add trend lines to a view, both axes must contain a field that can be interpreted as a number. For example, you cannot add a trend line to a view that has the Product Category dimension, which contains strings, on the Columns shelf and the Profit measure on the Rows shelf.
However, you can add a trend line to a view of sales over time because both sales and time can be interpreted as numeric values.

2) But, this isn't all right? We need to focus on the year 2013. This can be done by using the year column as it is (continuous) in the filter shelf, or by converting it to discrete first and then using it:
2.1 As it is (continuous)

2.2 Converting to discrete first & then using it

and then :

3) We can now see that France, with 485 has the 2nd most number of patents for the year 2013

NEW QUESTION # 150
You need to invert the color intensity of a quantitative range. Which option should you use?

A. Opacity
B. Border
C. Reversed
D. Stepped Color

Answer: C

Explanation:
To invert the color intensity of a quantitative range in Tableau, you should use the "Reversed" option. This option inverts the color scheme so that the colors representing the higher values are swapped with those representing the lower values. For example, if a color scale initially shows dark colors for high values and light colors for low values, using "Reversed" will switch this so that dark colors represent low values and light colors represent high values. This option is particularly useful for better visual distinction and interpretation in certain data scenarios.

NEW QUESTION # 154
You can use the __________________ in Tableau to clean / organise your data.

A. Data cleaner
B. Data manager
C. Data interpreter
D. Data organiser

Answer: C

Explanation:
When you track data in Excel spreadsheets, you create them with the human interface in mind. To make your spreadsheets easy to read, you might include things like titles, stacked headers, notes, maybe empty rows and columns to add white space, and you probably have multiple tabs of data too.
When you want to analyze this data in Tableau, these aesthetically pleasing attributes make it very difficult for Tableau to interpret your data. That's where Data Interpreter can help.

NEW QUESTION # 155
Given a map, which of the following fields can be placed in Size,Shape,Detail,Color

A. Region, Country, Profit, State
B. Longitude, Country, State, Sales
C. Sales, State, Country, Profit
D. Profit, State, Number of Records, Sales

Answer: C

Explanation:
Explanation
Since Sales is a measure, it can easily be depicted via size.
To drill down and change the level of detail, Country is the correct choice since it will contain STATE. We can then depict the various states by different shapes such as circle, square etc.
Finally, the Profit can be depicted via a color! Eg - Red for poor and green for excellent profits!

NEW QUESTION # 156
Which of the following points are True about Viz Animations?

A. They can be turned on for certain worksheets only
B. Animations work well with maps, polygons, and density marks in web
browsers
C. Sequential animations take more time but make complex changes
clearer by presenting them step-by-step
D. It is possible to turn them on for the entire workbook at once

Answer: A,C,D

Explanation:
All of the given options are true except - Animations work well with maps, polygons, and density marks in web browsers.
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 # 157
True or False: A LEFT JOIN or INNER JOIN creates a row each time the join criteria is satisfied, which can result in duplicate rows. One way to avoid this is to use data blending instead.

A. False
B. True

Answer: B

Explanation:
Joins combine tables by adding more columns of data across similar row structures. This can cause data loss or duplication if tables are at different levels of detail, and joined data sources must be fixed before analysis can begin.

Inner join

Left Join
Blends, unlike relationships or joins, never truly combine the data. Instead, blends query each data source independently, the results are aggregated to the appropriate level, then the results are presented visually together in the view.

NEW QUESTION # 158
Dates in Tableau are typically treated as ______________

A. Measures
B. Dimensions

Answer: B

Explanation:
For relational data sources, dates and times are automatically placed in the Dimensions area of the Data pane and are identified by the date or date-time icon. For example, the Order Date and Ship Date dimensions from an Excel data source are shown below:

When you place a relational date on a shelf, the field name is automatically modified to reflect the default date level. Tableau defines the default date level to be the level at which there are multiple instances. For example, if the date field includes multiple years, the default level is year. However, if the date field contains data for just one year but includes multiple months, then the default level is month.

Which of the following is NOT a valid official data source in Tableau Desktop?

A. SAP HANA
B. Amazon Redshift
C. Google Firebase
D. PostgreSQL

A. A bar chart
B. A pie chart
C. A text table
D. A line chart

Answer: A

NEW QUESTION # 162
You may create a context filter to:

A. Create a dependent numerical or top N filter
B. Improve performance
C. To create a dependent filter
D. To replace a data source filter

Answer: A,B

Explanation:
Important question! You cannot use a context filter to replace a data source filter since each filter type has its own use case. Also, a content filter is an Independent filter and all other filters are called dependent since they only process the data that passes through a context filter.
According to the official documentation :

NEW QUESTION # 165
For a relative date filter, the default anchor is _________________

A. The current time
B. The date we specify
C. The target date
D. Today's date

Answer: D

Explanation:
Relative date filters dynamically update to show a time period relative to when you open the view, such as the current week, the year to date, or the past 10 days. Relative date filters make it easy to create views that always show the most recent data.
Step 1: Drag a date field to the filter shelf
Right-click (control-click on Mac) and drag a date field from the Data window to the Filters shelf. In the Filter Field dialog box, click Relative Date, and then click Next.

Step 2: Select a time unit
In the Filter dialog box, click Relative dates, and then select the unit of time for the filter. For example, to show only the three most recent weeks, select Weeks.

Here, you can clearly see that the default date is TODAY

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 URLs.

NEW QUESTION # 168
Using the Time Series table, create a chart that shows the percent difference in Average Inventory on Hand for each Assortment by year and quarter.
How many quarters did the Electronics Assortment show a negative percent difference in the Average Inventory On Hand?

A. 0
B. 1
C. 2
D. 3

Answer: B

Explanation:
If you chose 2, then you were very close but probably didn't plot the actual Percent Difference on your view. ( One of the marks is just over the line).
Firstly, Drop the Week ID onto the column shelf, and convert it to continuous since we need both Year and Quarter as mentioned in the question.
2) Next, Drop assortment to filters shelf so that we can focus on Electronics!

3) This should be your view now. Click on the Show Mark Labels icon as shown:
The final view is as follows, with 3 points below 0 ( i.e negative )
