Suppose you have a bar chart. When we group by labels in a view, which of the following happens?
Answer(s): D
*Very important question*If we select the labels in the view and then group, a new consolidated mark is created - in our case bar since we are talking about a bar chart in the question. See below:Then on grouping, a new bar is created, and the colour of all bars remain the same.Had we grouped by choosing the marks instead of the labels, the following would be the result:

How can you add color to marks in the view in Tableau?
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.
Which of the following calculations DO NOT need a quick table calculation?
Answer(s): A,D
For Standard Deviation and Variance, we don't need to use quick table calculations, since they are available by default. See below:However, as seen in the types of quick table calculations available in Tableau, Rank and Moving Average belong to only this category.
Are animations enabled by default in Tableau?
Answer(s): A
No, by default, animations are not enabled in Tableau. We can animate visualizations to better highlight changing patterns in your data, reveal spikes and outliers, and see how data points cluster and separate. Animations visually transition between filter, sort, and zoom settings, different pages, and changes to filter, parameter, and set actions. As visualizations animate in response to these changes, viewers can more clearly see how data differs, helping them make better informed decisions.When you author animations, you can choose between two different styles: simultaneous or sequential. Here are examples of each type.1) Simultaneous animationsThe default simultaneous animations are faster and work well when showing value changes in simpler charts and dashboards.2) Sequential animationsSequential animations take more time but make complex changes clearer by presenting them step- by-step.To Animate visualizations in a workbook:1) Choose Format > Animations.2) If you want to animate every sheet, under Workbook Default, click On. Then do the following:For Duration, choose a preset, or specify a custom duration of up to 10 seconds.For Style, choose Simultaneous to play all animations at once or Sequential to fade out marks, move and sort them, and then fade them in.3) To override workbook defaults for a particular sheet, change the settings under Selected Sheet.
