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


These can be calculated using : Table(across), Cell, or Specific dimensions!

Explanation
Cluster analysis partitions marks in the view into clusters, where the marks within each cluster are more similar to one another than they are to marks in other clusters.

Explanation
According to Tableau's order of operations, the Extract filter is right at the top of the hierarchy. The data filtered in the Extract is then passed on to what we see in the Data Pane. See below:

Explanation
THIS IS A VERY IMPORTANT QUESTION
To answer this question, you need to understand Tableau's Order of Operations. See below and remember this always:

Explanation
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 animations
The default simultaneous animations are faster and work well when showing value changes in simpler charts and dashboards.

2) Sequential animations
Sequential 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.
