INTRODUCTION – Bringing Data to the User

In this module, you will be introduced to dashboards and gain an understanding of how they differ from reports, along with learning the processes of publishing and exporting reports. You will explore the distinct functions and advantages of dashboards, which provide a high-level overview of key metrics and performance indicators, in contrast to reports that offer more detailed and in-depth data analysis.

Additionally, this module will guide you through the steps required to publish your reports, making them accessible to your intended audience, and export them in various formats for sharing and presentation purposes. By the end of this module, you will be proficient in differentiating between dashboards and reports, as well as effectively managing the publication and exportation of your reports to ensure they reach and impact your stakeholders effectively.

Learning Objectives

  • Design accessible dashboards
  • Share and export report data

SELF-REVIEW: BUILDING A DASHBOARD

1. In the context of Adventure Works, what does pinning live reports to the executive dashboard accomplish?

  • It sends the dashboard to all employees of Adventure Works.
  • It updates the visual design of the dashboard, making it more appealing for the CEO.
  • It ensures that dynamic and interactive data is readily available to the CEO. (CORRECT)

That’s correct! In the context of Adventure Works, pinning live reports from the three reports to the dashboard ensures that dynamic, interactive data is readily available to the CEO. 

2. When building the Power BI executive dashboard for Adventure Works, what step followed uploading the pre-made reports to the Power BI service?

  • Share the dashboard
  • Add Quick Insights
  • Delete the original reports to avoid duplication
  • Create a new dashboard  (CORRECT)

That’s correct! The step that followed uploading the pre-made reports was to create a new dashboard. 

3. Based on the Product Stock by Customer Feedback visual generated using Quick Insights, what is the product stock count for the Positive feedback category? 

  • 486
  • 571 (CORRECT)
  • 306
  • 189

That’s correct! The value 571 corresponds to the product stock count associated with the Positive feedback category, suggesting a strong positive customer response.

4. How does a report in Power BI differ from a dashboard?     

  • There is no difference between a report and a dashboard in Power BI.
  • A dashboard in Power BI allows for interactive analysis, while a report does not.    
  • A report is an in-depth, interactive view of a specific dataset, while a dashboard provides a summary of the most important metrics. (CORRECT) 
  • A report provides a summary of the most important metrics, while a dashboard is an in-depth, interactive view of a specific dataset.

That’s correct! Reports provide an in-depth, multi-perspective view of a specific dataset or topic. A dashboard is a one-page view of important metrics or KPIs selected from various pages of one or more reports.

5. In configuring the mobile layout for a Microsoft Power BI dashboard, how do you select which visuals to show on the mobile layout?

  • The visuals are automatically chosen by Power BI based on their related data.
  • By selecting the pin icons next to the desired visualizations. (CORRECT)
  • The visuals are chosen based on their alignment with the dashboard’s theme.     
  • The visuals that fit best within the mobile screen size are automatically selected.     

That’s correct! Each visualization on a dashboard has a pin icon associated with it. By selecting the pin icons, you can choose specific visualizations from the dashboard to be included in the mobile layout.

6. What is the primary role of the Quick Insights feature in Power BI?

  • To store additional data for future analysis.
  • To ask questions about the dataset in plain English.
  • To automatically search datasets and visualize potential insights. (CORRECT)
  • To immediately implement changes in the dataset.

That’s correct! Quick Insights automatically scans your datasets and uncovers potential patterns, trends, and other insights that may not be immediately obvious.

7. What is the primary limitation of pinned visuals in Power B

  • They are not visually appealing.    
  • They are challenging to create.   
  • They lack interactivity. (CORRECT)
  • They can only show limited data.     

That’s correct! Pinned visuals are static snapshots that don’t update or interact, limiting usability and preventing interactive data analysis, cross-filtering, or drilling through data.

KNOWLEDGE CHECK: CREATING DASHBOARDS

1. How does a dashboard differ from a report in Microsoft Power BI?

  • A report is a one-page view of the most important metrics or key performance indicators (KPIs) selected from one or more dashboards.
  • A report is less interactive than a dashboard.
  • Unlike a report, a dashboard provides an in-depth, interactive, multi-perspective view of a specific dataset.
  • A dashboard is a one-page view of the most important metrics or key performance indicators (KPIs) selected from various pages of one or more reports. (CORRECT)

That’s correct! A dashboard is like a summary or highlight reel that provides a one-page view of the most important metrics or KPIs selected from the various pages of one or more reports.

2. What is the initial step for creating a new report after importing your data in Microsoft Power BI?

  • Select the Workspace and then create a new report (CORRECT)
  • Configure the mobile layout of your report
  • Change the theme of your dashboard

  • Import and clean your data for analysis
  • Automatically search datasets to discover and visualize potential insights
  • Ask questions about your data in plain English (CORRECT)
  • Manually create charts and graphs

That’s correct! The Q&A feature in Power BI is a natural language processing tool that allows users to ask questions about their data and get immediate answers in various formats, including charts, graphs, or simple numeric results.

5. What is the advantage of pinning live reports to your Microsoft Power BI dashboard over pinning static visuals?

  • Live reports automatically update every minute.
  • Live reports maintain the interactivity of the original report. (CORRECT)
  • You can pin live reports to multiple dashboards.
  • Live reports display only a single type of visualization.

That’s correct! Unlike standard visuals pinned to a dashboard, live report tiles are dynamic and maintain the interactivity of the original report.
