問題 #22
Yes or No: The number of marks will increase when you increase the number of Dimensions in a view

• A. No
• B. Yes

答案：B 解題說明：
Explanation
Of course! As an example, see below:
1) Using the Sample Superstore data, let's plot a bar chart showing the Sales for each Category:

Observe that we have 3 marks - Each bar in a bar chart is called a mark. Similarly, each point in a scatter plot is also a mark , and so on for all charts.
1 row by 3 columns means that clearly on the y-axis (Sales), we have only a single mark - a single continous axis, but 3 different marks (Technology, Furniture and Office supplies ) on the x-axis.
2) Now let's add subcategory to the view as well (another dimension):

Observe that the number of marks has increased - i.e the number of Bars.
Also, notice we now have 1 row and 17 columns. Simply because 1 row = Sales (on the y-axis), and on the x-axis, we have 17 different columns (i.e product sub categories!!)
問題 #23
Using the Time-series table, create a cross tab showing the Sales for each Item Number-ID, broken down by Assortments, then add Grand totals to the view. Which Item Number ID made the maximum sales across all assortments?

• A. 0
• B. 1
• C. 2
• D. Correct)
• E. 3

答案：A 解題說明：
Explanation
Follow along the steps below:
* Drag Assortment and Year ID to the column shelf, and Item Number ID to the row shelf. Next, drag Sales to the Text label to create a cross-tab as below:
問題 #24
How would you calculate GDP per capita in Tableau?

• A. SUM([GDP]/[POPULATION])
• B. SUM([GDP]) / SUM([Population])
• C. SUM([GDP]*[POPULATION])
• D. SUM([Population]/[GDP]])

答案：B 解題說明：
Explanation
GDP / Population = GDP Per Capita

Here Sum is a function, / and + are operators. On the bottom there are comments.
問題 #25
Question 30: Skipped
Using the CoffeeChain table, create a scatter plot of Profit (x-axis) vs Sales (y-axis) broken down by State.
Add a Linear trend line to the view. What is its R-squared value?

• A. 0.739284
• B. 0.748472
• C. 0.759329
• D. 0.783262

答案：D 解題說明：
Explanation
Trend lines have become popular questions in recent Tableau examinations. Follow along:
1) First drag Sales to the Rows shelf and Profit to the Columns shelf:

c
You will only see a single mark since the view is aggregated.
2) Now, break down this view by state. Drag State into Detail on the Marks shelf ( or directly to the view):

3) Finally, move to the Analytics pane, and drag Trend line to the view. When you drag it, select the Linear option!:


4) The following is our view. Hover over the trend line to see the R-squared value:

問題 #26
Which of the following is NOT a new feature introduced in Tableau 2020.1?

• A. Viz Animations
• B. Dynamic Paramaters
• C. Set Control
• D. Buffer Calculations

答案：C 解題說明：
Explanation
Your Tableau Desktop Specialist exam will be based on the 2020.1 version.
Set controls are a new feature introduced in the 2020.2 version, and hence is the correct answer - it is not a part of 2020.1 For the 2020.1 version the new features were:
1) Viz animations:
Viz animations help you see and understand your changing data. It's easy to track the logical steps behind data's evolution and tell powerful data stories. Sorting, filtering, adding fields, and other actions will now smoothly animate your visualizations. Choose whether to turn Viz Animations on or off, and decide how you'd best like to apply animations to your new workbooks.

2) Dynamic Parameters:
Say goodbye to republishing workbooks with parameters every time the underlying data changes. Set your parameter once, and Tableau will automatically update the parameter's list of values every time someone opens the workbook.

3) Buffer Calculations:

Buffer calculations allow you to visualize the distance around point locations. Give Tableau three parameters-location, distance, and a unit of measure-and a buffer, or boundary is instantly created.
Answering complex spatial questions becomes easier than ever before-visualize what properties are within
200 meters of a proposed transit site, or how many competitors' stores are within 1 mile of their store, and more.
