質問 # 41
Tableauの日付は通常、______________として扱われます
- A. 対策
- B. 寸法
正解:B
解説:
Explanation
For relational data sources, dates and times are automatically placed in the Dimensions area of the Data pane and are identified by the date or date-time icon. For example, the Order Date and Ship Date dimensions from an Excel data source are shown below:
When you place a relational date on a shelf, the field name is automatically modified to reflect the default date level. Tableau defines the default date level to be the level at which there are multiple instances. For example, if the date field includes multiple years, the default level is year. However, if the date field contains data for just one year but includes multiple months, then the default level is month.
質問 # 42
Tableau で抽出を作成するときの「増分更新」について正しいのは次のうちどれですか?
- A. 前回の更新以降に新しい行のみを追加します。
- B. 大規模なデータセットでのみ使用できます
- C. 違いはありません。抽出を使用する場合はどちらも同じです。ライブ接続を使用する場合は異なります。
- D. 抽出内のすべての内容を置き換えます。
正解:A
解説:
Extracts are saved subsets of data that you can use to improve performance or to take advantage of Tableau functionality not available or supported in your original data. When you create an extract of your data, you can reduce the total amount of data by using filters and configuring other limits. After you create an extract, you can refresh it with data from the original data.
When refreshing the data, you have the option to either do a full refresh, which replaces all of the contents in the extract, or you can do an incremental refresh, which only adds rows that are new since the previous refresh.
質問 # 43
表計算や計算フィールドを必要とせずに使用できる集計はどれですか?
- A. 合計のパーセント
- B. サンプルの共分散
- C. 標準偏差
- D. 現在の合計
正解:C
解説:
Standard deviation is an aggregation that is available without requiring a table calculation or calculated field.
Standard deviation is a statistical measure that shows how much variation there is from the average value in a set of data. Standard deviation is one of the predefined aggregations in Tableau that can be applied to any measure by selecting it from the context menu of the measure or from the drop-down menu on the Marks card6 The other options are not aggregations that are available without requiring a table calculation or calculated field. Running total, sample covariance, and percent of total are all examples of table calculations, which are computations that are applied to the values in an entire table or partition of a table. Table calculations can be created by selecting them from the context menu of a measure or by using functions in a calculated field7

質問 # 46
Tableauのストーリーポイントは何ですか?
- A. ダッシュボードのコレクション
- B. ワークシートのコレクション
- C. ワークシートとダッシュボードの両方のコレクション
- D. 単一のワークシートまたはダッシュボード
正解:D
解説:
Explanation
In Tableau, a story is a sequence of visualizations that work together to convey information. You can create stories to tell a data narrative, provide context, demonstrate how decisions relate to outcomes, or to simply make a compelling case.
A story is a sheet, so the methods you use to create, name, and manage worksheets and dashboards also apply to stories (for more details, see Workbooks and Sheets). At the same time, a story is also a collection of sheets, arranged in a sequence. Each individual sheet (worksheet or dashboard) in a story is called a story point.
When you share a story -for example, by publishing a workbook to Tableau Public, Tableau Server, or Tableau Online-users can interact with the story to reveal new findings or ask new questions of the data.
質問 # 47
固定の詳細レベル (LOD) 式に影響を与えるフィルタのタイプはどれですか?
- A. 測定フィルター
- B. ディメンションフィルター
- C. 表計算フィルター
- D. コンテキストフィルター
正解:B
解説:
In Tableau, a Fixed Level of Detail (LOD) expression calculates values at a specific level of granularity, regardless of the dimensions in the view. The computation of a fixed LOD expression can be influenced by a context filter. A context filter serves as a primary filter, setting the context for the rest of the filters in the view.
When a context filter is applied, it effectively changes the level at which the fixed LOD expression is computed, thereby affecting its outcome. Other types of filters, such as table calculation, measure, and dimension filters, do not have this influence on fixed LOD expressions.
質問 # 48
ビンを作成するオプションはどのタイプのフィールドで使用できますか?
- A. 日付
- B. 文字列
- C. 数値
- D. ブール値
正解:C
解説:
The option to create bins in Tableau is available for numeric fields. Bins allow you to group a series of numeric values into larger segments, which can simplify analysis and help in creating histograms or other visualizations that show the distribution of data. For example, you can create bins to group ages into categories like 0-10, 11-20, etc.
質問 # 49
Tableau で日付フィルターを作成する場合、アンカーとは何を指しますか?
- A. データ ソース内で見つかった最新の日付。
- B. 時間単位を固定する日付範囲フィルター内の日付。
- C. 時間単位を固定する相対日付フィルター内の日付。
- D. 表示される日付範囲の中間点。
正解:C
解説:
When creating a date filter in Tableau, anchor refers to the date in a relative-date filter to which you anchor a unit of time. A relative-date filter is a type of filter that allows you to dynamically filter data based on a range of time relative to the current date or a specific date. For example, you can use a relative-date filter to show data for the last 7 days, the next 3 months, or the current quarter1 To create a relative-date filter, you need to specify the following options: The date field that you want to filter. The unit of time that you want to use for the filter, such as days, weeks, months, quarters, or years. The range of time that you want to show relative to the anchor date, such as last, next, this, or to date. The anchor date that you want to use as the reference point for the filter. You can use the current date or a custom date as the anchor date1 For example, if you want to create a relative-date filter that shows data for the last 3 months from January 1st, 2022, you would select the following options: Date field: Order Date Unit of time: Months Range of time: Last 3 Anchor date: Custom (01/01/2022) 1 The other options are not valid definitions of anchor when creating a date filter in Tableau. The mid-point in the range of displayed dates is not related to the anchor date, but rather to the center of the axis that represents the date field. The date in a range-of-dates filter to which you anchor units of time is not correct, because a range-of-dates filter does not use an anchor date, but rather a start and end date that can be fixed or dynamic. The latest date in the data source that can be found is not related to the anchor date, but rather to the maximum value of the date field in the data source2

正誤問題:フィールドを連結するには、フィールドが同じデータ型である必要がある
- A. 本当
- B. 偽
正解:A
解説:
Explanation
Yes! To concatenate fields, they must be of same data type. However, there is a workaround which we can use
- Type casting. See below:
Here, State and City are Strings, but Postal Code? Nope. It's an Integer. So we can simply use the STR() function to convert it into a String, and hence the entire equation becomes valid!

質問 # 57
定量的範囲の色の強度を反転する必要があります。どのオプションを使用する必要がありますか?
- A. 境界線
- B. ステップカラー
- C. 不透明度
- D. 反転
正解:D
解説:
To invert the color intensity of a quantitative range in Tableau, you should use the "Reversed" option. This option inverts the color scheme so that the colors representing the higher values are swapped with those representing the lower values. For example, if a color scale initially shows dark colors for high values and light colors for low values, using "Reversed" will switch this so that dark colors represent low values and light colors represent high values. This option is particularly useful for better visual distinction and interpretation in certain data scenarios.
質問 # 58
ビジュアライゼーションを作成するには、まず行にメジャーを追加します。次に、11 メンバーのディメンションを列に追加します。
すべての寸法がゼロ以外の値を持つと仮定すると、寸法を追加する前後でビューにマークがいくつ存在するでしょうか?
- A. 前に 1 つ、後から 12 つ
C 前 1 と後 11 - B. 前に 1 つ、後に 2 つ
- C. 前に 2 つ、後から 11 つ
正解:C
解説:
In Tableau, when you initially add a measure to the rows shelf, you create one mark in the view that represents the aggregate value of that measure. When you then add a dimension with 11 members to the columns shelf, the view is subdivided into 11 separate marks, each representing the measure for one of the dimension members. This results in a total of 11 marks in the view after the dimension is added, one for each member of the dimension.
