NEW QUESTION 78
______________ is a method for appending values (rows) to tables. You can use this method if both tables have the same columns. The result is a virtual table that has the same columns but extends vertically by adding rows of data.

 Joining

 Blending

 Combining

 Unioning

Explanation
Unioning is the correct answer!
From the official documentation:

For example, suppose you have the following customer purchase information stored in three tables, separated by month. The table names are “May2016” , “June2016” and “July2016.”

NEW QUESTION 79
Which of the following would you use to connect to multiple tables in a single data source at once?

 A Blend

 A Hierarchy

 A Set

 A Join

Explanation
The data that you analyze in Tableau is often made up of a collection of tables that are related by specific fields (that is, columns). Joining is a method for combining data on based on those common fields. The result of combining data using a join is a virtual table that is typically extended horizontally by adding columns of data.
For example, consider the following two tables originating from a single data source:

We can combine these 2 tables, simply by joining the tables on ID to answer questions like, “How much was paid in royalties for authors from a given publisher?”. By combining tables using a join, you can view and use related data from different tables in your analysis.

NEW QUESTION 80
A field that shows average home values for the United States in 2016 is most likely :

 A discrete date part dimension

 A continuous date value dimension

 A geographical dimension

 An aggregated measure

Explanation
This question is directly from the Official Tableau Desktop Specialist exam guide.
Since we are talking about the AVERAGE home values for the United States in 2016, the question is directly offering us a hint that the answer has something to do with aggregation and that too the values tell us that we’re working with MEASURES.
Date part and Date values don’t really make much sense given the question, and neither does geography.
Therefore, the answer naturally is “An aggregated measure”.

NEW QUESTION 81
What does the box in a box plot represent?

 Maximum value of the data

 Minimum value of the data

 The interquartile range

 The median of the middle half of the data points

Explanation
In a box and whisker plot:
1) The ends of the box are the upper and lower quartiles, so the box spans the interquartile range
2) The median is marked by a vertical line inside the box
3) The whiskers are the two lines outside the box that extend to the highest and lowest observations.

NEW QUESTION 82
Which of the following returns the Absolute Value of a given number?

 ABS(Number)

 CEILING(Number)

 FLOOR(Number)

 ZN(Number)

Explanation
From the official Tableau website:

NEW QUESTION 83

See below:

NEW QUESTION 84
Data blending simulates a traditional _________________ Join

 Inner

 Right

 Full Outer

 Left

Explanation
Data blending simulates a traditional left join. The main difference between the two is when the aggregation is performed. A join combines the data and then aggregates. A blend aggregates and then combines the data.

NEW QUESTION 86
For creating variable sized bins we use __________________

 Calculated Fields

 Table Calculations

 Sets

 Groups

Explanation
One way to view a measure in Tableau Desktop is to split it into bins. You can think of bins as buckets based on a range of values. For example, say you have a measure that represents age. Instead of aggregating the measure to calculate the average age, you can bin the measure to define age groups: 0-5, 6-10, 11-15, and so on. Then you can count the number of people in each age group.
Create a calculated field for variable bin size
Step 1
Select Analysis > Create Calculated Field.
Step 2
In the Calculated Field dialog box, complete the following steps:

NEW QUESTION 87
The row and column shelves contain ___________________

 Pills

 Grand Totals

 Filters

 Parameters

Explanation
We can drag fields from the Data pane to create the structure for your visualizations.
The Columns shelf creates the columns of a table, while the Rows shelf creates the rows of a table. You can place any number of fields on these shelves.
These FIELDS are also referred to as PILLS. See below:

NEW QUESTION 88
Using the dataset, create a bar chart showing the average Quantity broken down by Region, and filtered by Country to only show Japan. What was the average Quantity in the State of Tokyo?

 3.000

 3.840

 3.704

 3.500

Explanation
Since we need to focus on 1 country -> Japan, let’s filter on it first as follows:
1) Drag Country to the filter shelf, and choose only Japan. Click OK.

2) Read the Question Carefully, we need to break down the visualisation by Region, then by Country, and then by State. So let’s do that:
Drag Region to the column shelf, followed by Country. Drill down into Country to include states as well.
Then drag Quantity to the Row Shelf, and change the Aggregation to AVERAGE.
The following is our visualisation:

Now that you think of it, EVEN IF YOU REMOVE THE REGION, THE ANSWER REMAINS THE SAME.
Such elements will be present in the actual exam too, just to make the question sound a little difficult, but actually it is pretty straightforward 🙂

NEW QUESTION 89
For a relative date filter, the default anchor is _________________

 The current time

 Today’s date

 The target date

 The date we specify

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

NEW QUESTION 90
By definition, Tableau displays measures over time as a ____________

 Packed Bubble

 Bar

 Stacked Bar

 Line

Explanation
Line charts connect individual data points in a view. They provide a simple way to visualize a sequence of values and are useful when you want to see trends over time, or to forecast future values.
Please refer to the images below:

NEW QUESTION 91

 Portable Network Graphic (.PNG)

 JPEG Image (.JPG, .JPEG)

 Tagged Image File Format (TIFF)

 Windows Bitmap (.BMP)

Explanation

NOTE: When we Copy an image rather than exporting it, then the image is copied to the clipboard in the TIFF file format! However, it is not available when EXPORTING an image.

NEW QUESTION 92
Is SUM a table calculation?

 Yes

 No

Explanation
SUM is an aggregate function, not a table calculation!
A table calculation is a transformation you apply to the values in a visualization. Table calculations are a special type of calculated field that computes on the local data in Tableau. They are calculated based on what is currently in the visualization and do not consider any measures or dimensions that are filtered out of the visualization.
The most common Table calculations are:
Running Total
Percent Difference
Difference
Percent of Total
Rank
Percentile


These can be calculated using : Table(across), Cell, or Specific dimensions!

NEW QUESTION 93
What is the one most important thing you should do after creating a Dual-axis chart?

 Synchronise the axis

 Change the colours

 Edit the labels

 Hide the axis

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.
