Which of the following are FALSE about Joins?
- A . Joins can be defined at the time of query dynamically
- B . May drop unmatched measure values
- C . They are displayed with Venn diagram icons between physical tables
- D . Joined tables are never merged into a single table.
- E . They are a more dynamic way than relationships to combine data
A,D,E
Explanation:
According to the official documentation:
Joins are a more static way to combine data. Joins must be defined between physical tables up front, before analysis, and can’t be changed without impacting all sheets using that data source. Joined tables are always merged into a single table. As a result, sometimes joined data is missing unmatched values, or duplicates aggregated values.
Joins –
1) Are displayed with Venn diagram icons between physical tables
2) Require you to select join types and join clauses
3) Joined physical tables are merged into a single logical table with a fixed combination of data
4) May drop unmatched measure values
5) May duplicate aggregate values when fields are at different levels of detail
6) Support scenarios that require a single table of data, such as extract filters and
aggregation

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

Given a map, which of the following fields can be placed in Size,Shape,Detail,Color
- A . Profit, State, Number of Records, Sales
- B . Region, Country, Profit, State
- C . Longitude, Country, State, Sales
- D . Sales, State, Country, Profit
D
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!
