You have the following box plot that shows the distribution of average profits made in every state by region.

Which region has the smallest distribution of profits?

1. South

2. Cast

3. Central

4. West

Answer: C

Explanation:

The central region has the smallest distribution of profits because it has the smallest interquartile range (IQR), which is the distance between the first and third quartiles of the box plot. The IQR measures the spread of the middle 50% of the data. The smaller the IQR, the less variation in the data.

This will allow you to control who can access and interact with your dashboard, as well as schedule automatic refreshes of your data source or extract. Publishing to Tableau Public would expose your data to anyone on the internet, printing to PDF would not update your data, and exporting as a .twbx would require sending a large file that might not be compatible with other versions of Tableau.

Question: 15

You have the following dataset.

Which Level of Detail (LOD) expression should you use to calculate tie grand total of all the regions?

1. {FIXED: [Region] SUM Sales}

2. {FIXED: SUM Sales}

3. {Fixed: [Region]: TOTAL Sales}

4. {FIXED: TOTAL (Sales)}

Answer: D

Explanation:

To calculate the grand total of all the regions, you need to use a Level of Detail (LOD) expression that ignores any dimensions in the view and returns the total sum of sales. The FIXED keyword allows you to specify the level of detail for the calculation, and the TOTAL function returns the sum of all values in the expression. Therefore, the correct LOD expression is {FIXED: TOTAL (Sales)}.

You have the following sets in a Tableau workbook ⢠Top N Customers

⢠Customers of 2020 ⢠Top N Products

⢠Sellers of 2020

Which two sets can you combine? Choose two

1. Sellers of 2020

2. Customers of 2020

3. Top N Products

4. Top N Customers

Answer: A,B,D

Explanation:

To combine two sets, they must have at least one dimension in common. In this case, Customers of 2020 and Top N Customers both have Customer Name as a dimension, so they can be combined using set operations such as union, intersection, or difference. Sellers of 2020 and Top N Products have different dimensions (Seller Name and Product Name), so they cannot be combined.

You need to prepare the data to support the planned visualization. The data source must support being published. Which four actions should you perform in order? (Place the four correct options n order Use the arrows to move

Options to Answer Area arrows to re-order the options. Use Answer Area arrows to re-order the options)

wrong

Answer: A,B,D
Explanation:

The correct order of the four actions is:

Open Tableau Prep

Union the sales data of both divisions

Create a new column to concatenate the name for the Germany division Join the sales data and the population data by using Country as the join field

The first action is to open Tableau Prep, which is a tool that allows you to prepare and shape your data for analysis. You can connect to various data sources, clean and transform your data, and output it to Tableau Desktop or Tableau

Server.

The second action is to union the sales data of both divisions, which means appending them together. This will create a single table that contains all the rows from both tables, with null values for any missing fields. You can use the Union step in Tableau Prep to drag and drop your tables and create a union.

The third action is to create a new column to concatenate the name for the Germany division, which means combining the first name and last name into one field. This will make it consistent with the name field in the United States division, and allow you to identify each salesperson by their full name. You can use the Clean step in Tableau Prep to create a calculated field that uses the CONCAT function to join the two fields.

The fourth action is to join the sales data and the population data by using Country as the join field, which is a common field between them. This will add the population data for each country to the sales data, which is needed to calculate the sales per capita. You can use the Join step in Tableau Prep to drag and drop your tables and choose the join type and fields.
