Scenario 1, questions 1-9You have been working as a junior data analyst at Bowling Green Business Intelligence for nearly a year. Your supervisor, Kate, tells you that she believes you are ready for more responsibility. She asks you to lead an upcoming client presentation. You will be responsible for creating the data story, identifying the right tools to use, building the slideshow, and delivering the presentation to stakeholders.Your client is Gaea, an automotive manufacturer that makes eco-friendly electric cars. For the past year, you have been working with the data team in Gaea’s Bowling Green, Kentucky, headquarters. For the presentation, you will engage the data team, as well as its regional sales representatives and distributors. Your presentation will inform their business strategy for the next three-to-five years.A big part of audience engagement is knowing how to eliminate less important details. What practice do you use to scan quickly through the data in order to identify the most important insights?
Correct: You use spotlighting to scan through data to quickly identify the most important insights. Spotlighting enables data analysts to identify broad, universal ideas and messages. 2. Scenario 1, continuedYour team’s analysis has revealed three key insights:
Fill in the blank: Based on these insights, you create a clear and direct _____, which will guide your data story.
Correct: You create a clear and direct primary message, which will guide your data story. This aligns with best practices for writing a primary message. 3. Scenario 1, continuedNext, you decide on your data narrative’s characters, setting, plot, big reveal, and aha moment. During the narrative, you want to communicate to your stakeholders about the challenges associated with the current lack of vehicle charging stations and why it’s important for Gaea to increase its cars’ battery range by 2025.Information about charging stations and the need to increase battery range will be part of the setting of your data story.
Correct: This information will be part of the plot. The plot, or conflict, is used to create tension in the data story. For Gaea’s situation, it would include two ideas: An explanation of some of the challenges associated with lack of vehicle charging stations and details about why it’s important for Gaea to increase its cars’ battery range by 2025. 4. Scenario 1, continuedNow, it’s time to consider which tools to use to create data visualizations that will clearly communicate the results of your analysis. You and your team decide to make both spreadsheet charts and Tableau data visualizations. In addition, you want to provide them with a tool that will achieve the following goals:
What tool do you create for your stakeholders?
Correct: You create a dashboard. There are multiple benefits to using dashboards to tell data stories. They include being able to organize information from multiple datasets into one central location and enabling tracking and analysis of data. In addition, dashboards can simplify data visualization using tables, charts, and graphs. 5. Scenario 1, continuedNow that you have finished planning the data story with your team, it’s time to create data visualizations. First, you consider electric vehicle sales worldwide in 2015 compared to 2020. You use a spreadsheet to create the following bar graph to compare the two values:You add information on the x-axis to represent a scale of values for the total electric vehicle sales and on the y-axis to represent the time periods (2015 and 2020).
Correct: In bar graphs with vertical bars, the x-axis is used to represent time periods, categories, or other variables. The y-axis is used to represent a scale of values for the variables. 6. Scenario 1, continuedNext, you explore how access to public car-charging stations is influencing electric vehicle purchases. As your analysis has revealed, there are many areas without enough places for people to plug in and charge their cars. This lack of charging stations has a negative impact on demand for electric cars and overall vehicle sales.You use Tableau to create the following draft of a visualization, which organizes the charging station data geographically:After reviewing your draft, you realize that it could be improved. What steps do you take to make your map more effective? Select all that apply.
Correct: A map’s colors should be used to help the audience understand the data it contains. To make the map more effective, you make the intensity of the colors stronger, select more varied hues, and choose darker values. Intensity will make the colors brighter. Different hues will help the states stand out from one another. And darker values will make the color differences easier to see. 7. Scenario 1, continuedNow, you want to highlight what your team’s analysis discovered about the number of charging stations available compared to the number of cars purchased. Your data has confirmed that the lack of charging stations causes the effect of fewer car sales. To communicate this effectively, you will need to convey causation to the stakeholders.How do you explain causation?
Correct: Causation is when an action directly leads to an outcome, such as a cause-effect relationship. In the case of Gaea’s business, the lack of charging stations directly leads to the outcome of fewer car sales. 8. Scenario 1, continuedOnce you finish creating data visualizations about the current state of the electric vehicle market, you turn to projections for the future. You want to communicate to stakeholders about the importance of longer vehicle battery range to consumers.Your team’s data includes feedback from a consumer survey that investigated the importance of longer battery when choosing whether to purchase an electric car. The current average battery range is about 210 miles. By 2025, that distance is expected to grow to 450 miles per charge.You create the following pie chart:Fill in the blank: After reviewing your pie chart, you realize that it could be improved. You resize the _____ so they visually show the different values.
Correct: To make this chart more effective, you resize the segments so they visually show the different values. When the segments are all the same size, even though they represent different values, this will confuse the audience. 9. Scenario 1, continuedIt’s time to build your Tableau dashboard for stakeholders. You consider what type of layout to use.Describe the differences between vertical and horizontal layouts. Select all that apply.
Correct: Vertical layouts adjust the height of the views and objects contained. Horizontal layouts adjust the width of the views and objects contained. 10. Scenario 2, questions 10-15You have created your narrative and visuals, so now it’s time to build a professional and appealing slideshow. You choose a theme that matches the tone of your presentation. Then, you create a title slide with a title, subtitle, and the date.Next, you create the following slide that compares electric vehicle sales in 2015 and 2020:After reviewing your slide, you realize that it could be improved. What steps do you take to make the two text boxes beneath the header more effective? Select all that apply.
Correct: To make the text more effective, you should edit it to fewer than five lines and 25 words. You should also ensure the text on the slide does not simply repeat the words you say. 11. Scenario 2, continuedYou then create the following slide to demonstrate the challenges associated with battery range and charging stations:After reviewing your slide, you realize that the visual elements could be improved. Which of the following options would help you make the visual elements on this slide more effective? Select all that apply.
Correct: To make the visual elements more effective, you should choose one data point to share, then create another slide for the second data visualization. In addition, you should use a consistent font size and color for data visualization titles. 12. Scenario 2, continuedYou complete your slideshow and share it with your team. Once it is approved by your supervisor, you prepare to give your presentation. You consider presentation best practices: maintaining good posture, being aware of nervous habits, and making eye contact. In addition, you think about how you will present your data visualizations.What strategies can help you explain the data visualizations effectively? Select all that apply.
Correct: To make sure you explain the data visualizations effectively, channel your excitement, start with the broader ideas, and use the five-second rule. Correct: To explain the data visualizations effectively, you should channel your excitement, start with the broader ideas, and use the five-second rule. 13. Scenario 2, continuedNext, you prepare for the question-and-answer session that will follow your presentation. What methods help you predict what questions your audience may ask? Select all that apply.
Correct: To predict what questions stakeholders may ask, make sure you have a clear understanding of Gaea stakeholder objectives. You should also do a test-run of your presentation and consider and describe any limitations of your data. 14. Scenario 2, continuedNow that you have some idea of the questions the stakeholders will ask, you consider potential objections. You and a team member consider different objections that might arise. Your team member asks you how you will respond if someone from Gaea has an objection that you haven’t prepared for.You say that you will respond professionally using the information you currently have available in order to move quickly past the objection.
Correct: If you are unprepared to respond to an objection, you should acknowledge that the objection is valid. Then, you can let the Gaea team know you will investigate further and follow up with more details. 15. Scenario 2, continuedThe big day has arrived, and you have just finished giving your presentation to the Gaea team. It’s now time for the question-and-answer session, and a stakeholder asks you a very detailed question about one specific electric vehicle charging station initiative.You listen to the whole question, then repeat it. For what reasons is this important? Select all that apply.
Correct: Listening to the whole question and repeating it helps you confirm that you understand the question. It also gives the stakeholder a chance to correct you if you are misunderstanding and ensures the entire audience has heard the question.
