Which of the following charts types always includes bars sorted in descending order?

  1. Pareto Chart
  2. Pie Chart
  3. Gantt Chart
  4. Stacked Bar Chart

Answer(s): A

Explanation:

A Pareto chart is a type of chart that contains both bars and a line graph, where individual values are represented in descending order by bars, and the ascending cumulative total is represented by the line.
On the primary axis, bars are used to show the raw quantities for each dimension member, sorted in descending order.
On the secondary axis, a line graph is used to show the cumulative total in percent format.

True or False: It is possible to change the Geographic Role of a dimension

  1. True
  2. False

Answer(s): A

Explanation:

A geographic role associates each value in a field with a latitude and longitude value.
Assigning a geographic role based on the type of location (such as state versus postcode) helps ensure that your data is plotted correctly on your map view. For example, you can assign the City geographic role to a field that contains a list of city names.

To assign a geographic role to a field:


In the Data pane, click the data type icon next to the field, select Geographic Role, and then select the geographic role you want to assign to the field.

When you assign a geographic role to a field, Tableau adds two fields to the Measures area of the Data pane: Latitude (generated) and Longitude (generated).
These fields contain latitude and longitude values and are assigned the Latitude and Longitude geographic roles. If you double-click each of these fields, Tableau adds them to the Columns and Rows shelves and creates a map view using the Tableau background map.

The calculation [Ship Date] - [Order Date] will return____________.

  1. Number of orders placed in that duration
  2. Number of days between these dates
  3. Number of unique orders placed between these dates
  4. Number of orders shipped between these dates

Answer(s): B

Explanation:

As the names suggest, if we subtract the order date from the shipping date, we simply get the number of days between these 2 dates.

We can these use this calculated field in our charts, and can use COUNT, SUM, AVG etc with them according to our need.



What term is used to describe the following picture?

  1. Parameter
  2. Set
  3. Hierarchy
  4. Group

Answer(s): C

Explanation:

When you connect to a data source, Tableau automatically separates date fields into hierarchies so you can easily break down the viz. You can also create your own custom hierarchies. For example, if you have a set of fields named Region, State, and County, you can create a hierarchy from these fields so that you can quickly drill down between levels in the viz.
