To achieve the requirement of letting users navigate between different published dashboards directly from their current dashboard, you need to enable the "Show sheets as tabs" option. This setting allows each sheet in your workbook, including dashboards, to be displayed as a tab, making it easy for users to switch between different views or dashboards within the same published workbook.

Here is the option you should configure:

Check the Show sheets as tabs checkbox in the 'More Options' section.

This action will ensure that all sheets, when published to the Tableau Server, appear as tabs, facilitating user navigation across multiple dashboards included in the workbook.

Tableau Prep's Grouping feature includes various methods to group similar data. The Spelling option is used when the data has small variations in spelling, such as capitalization differences or common typos. Given that the names in the dataset vary in capitalization and punctuation but are spelled correctly, the Spelling grouping option would be the most appropriate choice to automatically group all five names.

To build the scatter plot shown in the image, you need to place the Profit measure on the Rows shelf and the Sales measure on the Columns shelf. This will create a Cartesian chart with Profit as the y-axis and Sales as the x-axis. Then, you need to change the mark type to Circle on the Marks card. This will display the data points as circles that vary in size according to the Quantity measure. You can also add color or shape encoding to the marks to show additional dimensions or measures in the view. References:

To combine the two tables that contain data about books in a library and ensure that all the data is retained, you should use a full outer join. A full outer join is a type of join that returns all rows from both tables, regardless of whether there is a match or not. If there is no match, null values are filled in for the missing fields.

To perform a full outer join, you need to do the following steps:

Connect to both tables as your data sources in Tableau. You can use either live or extract connections.

Drag one table to the canvas and drop it on top of another table. This will create a join between them based on a common field.

Click on the join icon between the tables and select Full Outer Join from the drop-down list. This will change the join type to full outer join and show all rows from both tables.

Optionally, you can add or remove join clauses by clicking on Add or Remove buttons next to each clause. You can also change or rename fields by clicking on them.

The other types of joins are not correct for this scenario. An inner join returns only the rows that have a match in both tables, which will exclude any books that are missing from either table. A left join returns all rows from the left table and only the matching rows from the right table, which will exclude any books that are only in the right table. A right join returns all rows from the right table and only the matching rows from the left table, which will exclude any books that are only in the left table.

When combining two datasets that are both incomplete and where it's important to retain all data from both sources, a full outer join is appropriate. This type of join ensures that all records from both tables are included in the combined dataset, even if there are no matching records in the other table.
