What is the following icon in the Data pane used to do?Larger image
Answer(s): A
View Data allows you to inspect your data in a spreadsheet-like layout. You can view data either for the data source as a whole, or to see the underlying data for an individual mark or a group of marks. In a worksheet, the rows that you see in the View Data window are always scoped to the current selection or the current view.The View Data window displays as much of the data as possible by default, up to 10,000 rows. Field names are shown as column headers and can be dragged and dropped to change their display order. Click a column header to sort the values in that column.From the official website:

Yes or No: The number of marks will increase when you increase the number of Dimensions in a view
Answer(s): B
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!!)
Which of the following are valid ways of Grouping Data?
Answer(s): A,B,D
**IMPORTANT QUESTION AND EXPLANATION, PLEASE READ**3 ways to group data -1) Marks2) Labels3) Dimensions shelf.*IMPORTANT*If we Group the data by selecting the marks, then they remain separate marks in the view and then have the same colour. Also, a new group is created in the Dimensions shelf. Example -Using the sample superstore dataset, first plot a bar chart showing sales for each sub-category:Here, if we Select Phones, Chairs and Storage by selecting the MARKS (Bars), and then group them:They remain seperate marks (BARS) but are grouped by the same colour. Now, if we didn't do this, and rather grouped by selecting their Labels (Names):Then they no longer remain separate Marks (bars) but are rather consolidated into a single Bar:Finally, we can group directly from the Dimensions shelf as follows:Now choose Phones, Chairs and Storage and Click Group:You will now automatically have a new Dimension as follows:

Which of the following would you use to edit the Shape, colour, and Text of your visualisations?
The Marks Card allows us not only to edit the Shape, Text and Colour, but also to modify the Tooltip and the level of detail of the visualisation!The Marks card is a key element for visual analysis in Tableau. As you drag fields to different properties in the Marks card, you add context and detail to the marks in the view.You use the Marks card to set the mark type (see Change the Type of Mark in the View), and to encode your data with color, size, shape, text, and detail. To change the mark settings, see Control the Appearance of Marks in the View.In this example, three different fields have been dragged to different properties in the Marks card. Segment is on Color, Region is on Shape, and Quantity is on Size. After you add a field to the Marks card, you can click the icon next to the field to change the property it is using. You can also click the property buttons in the Marks card to change those settings.Many properties can have multiple fields. For example, you can add multiple fields to Label, Detail, Tooltip, and Color. Size and Shape can only have one field at a time. For more details, see Control the Appearance of Marks in the View.

Question 45: SkippedYou have just created a histogram and now want to be able to change the size of bins dynamically. Using which of the following will easily satisfy your requirement?
Answer(s): D
A parameter is a global placeholder value such as a number, date, or string that can replace a constant value in a calculation, filter, or reference line.For example, you may create a calculated field that returns True if Sales is greater than $500,000 and otherwise returns False. You can replace the constant value of "500000" in the formula with a parameter. Then, using the parameter control, you can dynamically change the threshold in your calculation.For example -
