A. 偽
B. 本当

正解：B

解説：
Yes, it is possible to create worksheet-specific filters in Tableau.
When you add a filter to a worksheet, by default it applies to the current worksheet. Sometimes, however, you might want to apply the filter to other worksheets in the workbook.
Then, you can select specific worksheets to apply the filter to or apply it globally to all worksheets that use the same data source or related data sources.

質問 # 156
散布図を作成するには、少なくともいくつのメジャーが必要ですか?

A. 0
B. 1
C. 2
D. 3

正解：B

解説：
We can use scatter plots to visualize relationships between numerical variables!
In Tableau, you create a scatter plot by placing at least one measure on the Columns shelf and at least one measure on the Rows shelf (Total 2 minimum). If these shelves contain both dimensions and measures, Tableau places the measures as the innermost fields, which means that measures are always to the right of any dimensions that you have also placed on these shelves. The word "innermost" in this case refers to the table structure.

( Simple Scatter Plot)

(Matrix of Scatter Plots)
A scatter plot can use several mark types. By default, Tableau uses the shape mark type. Depending on your data, you might want to use another mark type, such as a circle or a square. For more information, see Change the Type of Mark in the View.
To create a scatter plot, follow the steps below:

質問 # 158
最初にフィルターを適用し、次に上位N要素または下位N要素を表示する場合、次のフィルターのどれを使用しますか？

A. コンテキストフィルター
B. これらのどれも
C. 抽出フィルター
D. データソースフィルター

正解：A

解説：
By default, all filters that you set in Tableau are computed independently. That is, each filter accesses all rows in your data source without regard to other filters. However, you can set one or more categorical filters as context filters for the view. You can think of a context filter as being an independent filter. Any other filters that you set are defined as dependent filters because they process only the data that passes through the context filter.
You may create a context filter to:
1) Improve performance - If you set a lot of filters or have a large data source, the queries can be slow. You can set one or more context filters to improve performance.
2) Create a dependent numerical or top N filter - You can set a context filter to include only the data of interest, and then set a numerical or a top N filter.

質問 # 159
正誤問題: カテゴリデータと定量データに対してさまざまなフィルターオプションが得られます。

A. 真
B. 偽

正解：A

解説：
Yes! We get different options for filtering depending on whether we use a categorical data (think dimension) or quantitative data (think measure).

Important Note: Each tab adds additional definitions to your filter. For example, you can select to exclude values under the General tab, and also add limits under the Top tab. Selections and configurations from both tabs are applied to your filter.At any time, you can see the definitions of your filter under Summary on the General tab.

Note: If you have a large data source, filtering measures can lead to a significant degradation in performance.
It is sometimes much more efficient to filter by creating a set containing the measure and then apply a filter to the set. For more information about creating sets, see Create Sets

質問 # 160

Tableauの__________________を使用して、データをクリーンアップ/整理できます。

A. データオーガナイザー
B. データクリーナー
C. データマネージャー
D. データインタプリタ

解説：
When you track data in Excel spreadsheets, you create them with the human interface in mind. To make your spreadsheets easy to read, you might include things like titles, stacked headers, notes, maybe empty rows and columns to add white space, and you probably have multiple tabs of data too.
When you want to analyze this data in Tableau, these aesthetically pleasing attributes make it very difficult for Tableau to interpret your data. That's where Data Interpreter can help.

質問 # 163
Tableau Desktopの有効な公式データソースではないものは次のうちどれですか？

A. Google Firebase

But then again, it is a workaround and not an official out-of-the-box solution.
The following are the available Data sources available as of now:
* Server

If you chose 2, then you were very close but probably didn't plot the actual Percent Difference on your view. ( One of the marks is just over the line).
Firstly, Drop the Week ID onto the column shelf, and convert it to continuous since we need both Year and Quarter as mentioned in the question.
2) Next, Drop assortment to filters shelf so that we can focus on Electronics!

質問 # 167
単純な散布図を作成するには、少なくとも何が必要ですか?

A. 列のディメンションと行のメジャー
B. 列のメジャーと行のメジャー
C. 列のディメンションと行のディメンション
D. 詳細のディメンションと列のメジャー

正解：B

解説：
To create a simple scatter plot in Tableau, you need to have a measure on Columns and a measure on Rows. A scatter plot is a type of visualization that shows the relationship between two numerical variables. In Tableau, you can create a scatter plot by placing at least one measure on the Columns shelf and at least one measure on the Rows shelf. The measures can be continuous or discrete, but they must be aggregated. The marks in the scatter plot represent the intersection of the values for each measure1 The other options are not valid ways to create a simple scatter plot in Tableau. A dimension on Detail and a measure on Columns will create a bar chart, not a scatter plot. A dimension on Columns and a measure on Rows will create a line chart or an area chart, depending on the mark type. A dimension on Columns and a dimension on Rows will create a text table or a heat map, depending on the mark type1

質問 # 168
正誤問題：LEFTJOINまたはINNERJOINは、結合基準が満たされるたびに行を作成するため、行が重複する可能性があります。これを回避する1つの方法は、代わりにデータブレンディングを使用することです。

A. 偽
B. 本当

正解：B

解説：
Explanation
Joins combine tables by adding more columns of data across similar row structures. This can cause data loss or duplication if tables are at different levels of detail, and joined data sources must be fixed before analysis can begin.

Inner join

Left Join
Blends, unlike relationships or joins, never truly combine the data. Instead, blends query each data source independently, the results are aggregated to the appropriate level, then the results are presented visually together in the view.
