Answer(s): A

Explanation:

Click on the Analytics tab on the left side of the workbook to open the Analytics pane. You will see a list of analytical objects that you can drag and drop onto your worksheet. Drag Distribution Band from the Analytics pane to Profit on the Rows shelf. This will add a distribution band on Profit that shows the average and confidence interval for each Sub-Category. Click on the Edit button on the distribution band to open the Edit Distribution Band dialog box. You will see options to customize your distribution band.
Change the Band From value to -1 and the Band To value to 1. This will change the distribution band to show the standard deviation from -1 to 1, which means one standard deviation below and above the average.
Click OK to apply the changes. You will see that the distribution band now shows a narrower range of values for Profit.

Create a histogram on the Quantity field by using bin size of 3.

  1. check the steps below in explanation.

Answer(s): A

Explanation:

To create a histogram on the Quantity field by using bin size of 3, you need to do the following steps:
Open the link to Book1 found on the desktop. This will open the Tableau workbook that uses the Superstore data source.
Click on the Histogram tab at the bottom of the workbook to open the Histogram worksheet. You will see a blank worksheet with no marks.
Right-click on Quantity in the Measures pane and select Create Bins from the menu. This will open a dialog box that allows you to create bins for the Quantity field. Bins are groups of values that are treated as one unit in a histogram.
Enter 3 in the Size of bins text box. This will set the bin size to 3, which means that each bin will contain values that are 3 units apart. For example, one bin will contain values from 0 to 2, another bin will contain values from 3 to 5, and so on.
Click OK to create the bins. You will see a new field named Quantity (bin) in the Measures pane with a # sign next to it.
Drag Quantity (bin) from the Measures pane to Columns on the worksheet. This will create a histogram that shows the distribution of Quantity by bins. You will see bars that represent the frequency or count of values in each bin.
Optionally, you can adjust the width, color, and labels of the bars by using the options on the Marks card. You can also add filters, tooltips, or annotations to enhance your histogram.

You have the following bar chart.



You want the chart to appear as shown in the Mowing exhibit.



What should you add?

  1. A reference band
  2. A reference line
  3. An average line
  4. A distribution band

Answer(s): B

Explanation:

A reference line is used in Tableau to display a line at a constant value or a computed value such as an average, median, minimum, or maximum in a bar chart. In this case, adding a reference line would allow you to show the median, upper quartile, and lower quartile, which corresponds to the changes shown in the bar chart.



DRAG DROP (Drag and Drop is not supported)
You conned to a Microsoft SQL Server database
You need to create a custom SQL query that retrieves rows from a table named Students Only students m the city of Berlin must be returned
How should you complete the query? (Drag the appropriate Options to the Answer Area and drop into the correct locations.)

  1. See Explanation for the Answer.

Answer(s): A

Explanation:

Select
Where
The correct way to complete the query is:
SELECT * FROM [dbo] . [Students]
WHERE [Students].[City] = `Berlin'
The SELECT statement is used to retrieve data from a table or a view. The * symbol means that all columns will be returned. The FROM clause specifies the table or view name and the schema name. The WHERE clause is used to filter the data based on a condition. The condition is [Students].[City] = `Berlin', which means that only rows where the City column of the Students table is equal to `Berlin' will be returned.
The other options are not relevant for this query. CAST is a function that converts a value from one data type to another. JOIN is a clause that combines data from two or more tables based on a common field. ON is a keyword that specifies the join condition. UNION is a set operation that combines the results of two or more queries into one result set.
