NEW QUESTION 84
True or False: To concatenate fields, they must be of same data type
- A. True
- B. False
Answer: A
Explanation:
Explanation
Yes! To concatenate fields, they must be of same data type. However, there is a workaround which we can use
- Type casting. See below:
Here, State and City are Strings, but Postal Code? Nope. It's an Integer. So we can simply use the STR() function to convert it into a String, and hence the entire equation becomes valid!
NEW QUESTION 85
How can you add color to marks in the view in Tableau?
- A. From the Data pane, drag a field to Color on the Marks card.
- B. From the Analytics pane, drag a model to Color on the Marks card.

Answer: A
Explanation:
Explanation
To assign a color to marks in the view, do the following:
From the Data pane, drag a field to Color on the Marks card.
Tableau applies different colors to marks based on the field's values and members. For example, if you drop a discrete field (a blue field), such as Category, on Color, the marks in the view are broken out by category, and each category is assigned a color.
If you drop a continuous field, such as SUM(sales), on Color, each mark in the view is colored based on its sales value.
NEW QUESTION 86

NEW QUESTION 87
Yes or No: The number of marks will increase when you increase the number of Dimensions in a view
- A. No
- B. Yes
Answer: B
Explanation:
Explanation
Of course! As an example, see below:
1) Using the Sample Superstore data, let's plot a bar chart showing the Sales for each Category:
Observe that we have 3 marks - Each bar in a bar chart is called a mark. Similarly, each point in a scatter plot is also a mark , and so on for all charts.
1 row by 3 columns means that clearly on the y-axis (Sales), we have only a single mark - a single continous axis, but 3 different marks (Technology, Furniture and Office supplies ) on the x-axis.
2) Now let's add subcategory to the view as well (another dimension):
Observe that the number of marks has increased - i.e the number of Bars.
Also, notice we now have 1 row and 17 columns. Simply because 1 row = Sales (on the y-axis), and on the x-axis, we have 17 different columns (i.e product sub categories!!)
NEW QUESTION 88

NEW QUESTION 97
When you want to first apply a filter and THEN show the Top N or Bottom N elements, which of the following filters would you use?
- A. Context Filter
- B. Extract Filter
- C. None of the these
- D. Data source Filter
Answer: A
Explanation:
Explanation
IMPORTANT QUESTION, PAY ATTENTION
By default, all filters that you set in Tableau are computed independently. That is, each filter accesses all rows in your data source without regard to other filters. However, you can set one or more categorical filters as context filters for the view. You can think of a context filter as being an independent filter. Any other filters that you set are defined as dependent filters because they process only the data that passes through the context filter.
You may create a context filter to:
1) Improve performance - If you set a lot of filters or have a large data source, the queries can be slow. You can set one or more context filters to improve performance.
2) Create a dependent numerical or top N filter - You can set a context filter to include only the data of interest, and then set a numerical or a top N filter.
NEW QUESTION 98
