True or False: A sheet cannot be used within a story directly. Either sheets should be used within a dashboard, or a dashboard should be used within a story.

  1. rue
  2. False

Answer(s): B

Explanation:

It is possible in Tableau to use a sheet within a story directly.
Moreover, 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.
At the same time, a story is also a collection of sheets, arranged in a sequence. Each individual sheet in a story is called a story point.

Which of the following is a good reason for using a bullet graph?

  1. Comparing the actual sales against the target sales
  2. Analysing the trend over a given time period
  3. Forecasting future sales
  4. Displaying the year-on-year growth in sales

Answer(s): A

Explanation:

A bullet graph is a variation of a bar graph developed to replace dashboard gauges and meters. A bullet graph is useful for comparing the performance of a primary measure to one or more other measures. Below is a single bullet graph showing how actual sales compared to estimated sales.

True or False: We can disaggregate the data, to see all of the marks in the view at the most detailed level of granularity

  1. True
  2. False

Answer(s): A

Explanation:

Whenever you add a measure to your view, an aggregation is applied to that measure by default. This default is controlled by the Aggregate Measures setting in the Analysis menu.
If you decide you want to see all of the marks in the view at the most detailed level of granularity, you can disaggregate the view. Disaggregating your data means that Tableau will display a separate mark for every data value in every row of your data source.

To disaggregate all measures in the view:
Clear the Analysis >Aggregate Measures option. If it is already selected, click Aggregate Measures once to deselect it.

What does the box in a box plot represent?

  1. Maximum value of the data
  2. Minimum value of the data
  3. The interquartile range
  4. The median of the middle half of the data points

Answer(s): C

Explanation:

In a box and whisker plot:
1) The ends of the box are the upper and lower quartiles, so the box spans the interquartile range
2) The median is marked by a vertical line inside the box
3) The whiskers are the two lines outside the box that extend to the highest and lowest observations.
