Data Visualization – Tableau/Python or R – You have been hired as a data analyst and one of your first tasks includes selecting a car, primarily for your use, that will become part of the company fleet..
INTRODUCTION
The purpose of this task is for you to visually showcase data by identifying appropriate sources of data, scraping and cleaning data, and presenting those data in different formats. As you complete this task, you will create a dashboard with multiple visualization formats, use your data to effectively tell a story, and justify the choices you make. Your choices will be based on the criteria in the scenario and requirements sections below. You will also submit a brief written response to explain how you chose to present your data and why your methods are appropriate.
You must submit all your data files (both raw and cleaned) in spreadsheet format (e.g., .csv, .xls, .xlsx). To scrape your data, choose reliable web sources and use tools common to the industry such as Python, R, or other industry standard tools. You should use Tableau to create all your graphic representations (e.g., scatter plots, bubble charts, density plots, histogram matrices, heat maps, parallel coordinate plots, multidimensional scaling). Submit these Tableau outputs as .pdf files. Use a word processor to create your accompanying written report, as outlined in the requirements. This report should be two pages long, formatted in 12-point Arial font, and double spaced. Submit the reports as a .doc, .docx, or .pdf file.
The following artifacts are required to be submitted as part of this task:
- data files (raw and cleaned) in spreadsheet format (.csv, .xls, or .xlsx)
- dashboard and graphical representations of each data set, as created in Tableau (.pdf)
- written response or data summary (.doc, .docx, or .pdf)
Your submission will not be evaluated if these three artifacts are not submitted in the proper format.
SCENARIO
You have been hired as a data analyst and one of your first tasks includes selecting a car, primarily for your use, that will become part of the company fleet. Your manager has already narrowed down the choices to four vehicles: a 2019 Ford Escape, 2019 Honda CRV, 2019 Hyundai Santa Fe, or 2019 Toyota Rav 4. Because you will purchase the car with company funds, your manager has asked you to select a vehicle based on the company’s criteria; however, your own criteria for choosing a car are different. You must use data visualization best practices to create a dashboard, using data you will scrape, and tell a story for your manager to support your car selection.
Criteria 1 (Company Criteria):
Safety features – weighted at 10
Maintenance cost – weighted at 5
Price point – weighted at 7
Criteria 2 (Your Criteria):
Insurance
Fuel Economy
Resale Value
Note: You should include your personal weighting for the individual aspects of your criteria as part of your response to the requirements below.
REQUIREMENTS
Your submission must be your original work. No more than a combined total of 30% of the submission and no more than a 10% match to any one individual source can be directly quoted or closely paraphrased from sources, even if cited correctly. An originality report is provided when you submit your task that can be used as a guide.
You must use the rubric to direct the creation of your submission because it provides detailed criteria that will be used to evaluate your work. Each requirement below may be evaluated by more than one rubric aspect. The rubric aspect titles may contain hyperlinks to relevant portions of the course.

- Combine all the data and submit with labeled ranges and weightings for all sixaspects of the criteria sets.
Data Presentation
- Present your data visually based on criteria 1 in threedata visualization or comparative graphic formats.
- Present your data visually based on criteria 2 in threedata visualization or comparative graphic formats.
- Create a dashboard with fourgraphic representations, using accurate patterns and proportions, of all of your data for all six aspects of the criteria in the scenario.
Written Response
- Justify your choice of the best vehicle based on all sixaspects from the two data sets, citing specific examples from your data to support your claims.
- Explain how you used elements of effective storytelling in your presentation. Be sure to include specific examples of how you used these elements to persuade your manager to purchase the car you have chosen.
