Have a look at the following image. When we right click a measure, we get the following options:
However, for a dimension (this is because theDATA TYPEof this dimension is a string:
But what if we have a dimension of typeNUMBER (NUMERIC DIMENSION)? See below:

Question 5
Which of the following would you use to connect to multiple tables in a single data source at once?
- A. A Blend
- B. A Hierarchy
- C. A Set
- D. A Join
Answer:
D
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.

Question 8
True or False: Trend lines can only be used with numeric or date fields
- A. True
- B. False
Answer:
B
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.

Question 9
True or False: All rows from both tables are returned in an INNER JOIN
- A. True
- B. False
Answer:
B
Explanation:
The INNER JOIN keyword selects all rows from both tables as long as there is a match between the
columns. Consider 2 tables "Orders" and "Customers".
If there are records in the "Orders" table that do not have matches in "Customers", these orders will
not be shown!

Question 10
12/209
Is SUM a table calculation?
- A. Yes
- B. No
Answer:
B
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
