Key Steps
- Dataset Selection: Choose a relevant publicly available dataset that interests you and is rich enough to explore various dimensions.
- Exploratory Analysis: Use data visualization techniques in Tableau to perform an exploratory analysis, highlighting trends, outliers, and relationships between variables.
- Insight Summarization: Based on the analysis, draft a report summarizing key observations and potential areas of further investigation.
- Documentation: Create a detailed document in a DOC file format that outlines your approach, analysis techniques, and final insights.
Evaluation Criteria
- Clarity and depth of the exploratory analysis.
- Ability to grasp and articulate key data trends.
- Quality and organization of the submitted DOC file.
- Demonstrated understanding of Tableau’s EDA capabilities.
This task is designed to take approximately 30 to 35 hours of work.

Make sure your analysis is both visual and narrative so that a reader who is new to your work can easily follow your thought process and findings.
Task Objective
This week, your challenge is to develop a comprehensive plan for designing an interactive Tableau dashboard. The focus is on the conceptualization and layout strategy rather than the actual dashboard creation. You will outline your approach for assembling visual elements, how they will interact, and their rationale based on insights derived from data.
Expected Deliverables
- A DOC file containing your detailed dashboard plan and design strategy.
- Mock-up sketches or flow diagrams embedded within your document.
Key Steps to Complete the Task
- Conceptualization: Start by defining the objectives and target audience for your dashboard. Identify the key metrics and visual elements that will best convey the data story.
- Layout Strategy: Draft a detailed layout plan including position, color schemes, and interaction points. Use diagrams or sketches to visually represent your design.
- Integration Rationale: Explain why specific visualizations have been chosen and how they interrelate to tell a coherent data story. Discuss how the design enhances user understanding.
- Documentation: Prepare a DOC file documenting your entire planning process, including mock-ups, design choices, and strategic insights.
Evaluation Criteria
- Detailed approach and clarity of the design strategy.
- Quality and creativity of the layout planning.
- Effective use of diagrams or mock-ups.
- Depth of reasoning in integrating different dashboard elements.
This assignment is designed to require 30 to 35 hours of engagement. Your DOC file should serve as a blueprint for building the actual dashboard in subsequent weeks, ensuring that every design decision is well-founded and systematically documented.
Objective
This week’s task focuses on the art of interactive data storytelling using Tableau visualizations. Your goal is to create a narrative through data that engages the target audience by effectively communicating insights in a sequential and logical manner.
Expected Deliverables
- A DOC file that details your data story approach and planned visual narrative.
- A description of interactive elements and how they support the narrative flow.
Key Steps to Complete the Task
- Data Story Concept: Define a clear, compelling narrative that you wish to communicate. Identify the key message, supporting insights, and target audience for your story.
- Visual Narrative Planning: Identify the sequence of visualizations that will form your dashboard. Explain how each visualization contributes to the story.
- Interactive Elements: Describe any interactive features such as filters, parameters, or dashboard actions. Explain how these features allow users to explore the narrative in greater depth.
- Document the Plan: Create a detailed DOC file that explains the narrative flow, the role of each visualization, and the integration of interactive elements. Use bullet points, diagrams, or flow charts as needed.
Evaluation Criteria
- Coherence and clarity of the narrative design.
- Innovative use of interactive elements to enhance the data story.
- Depth of analysis and planning documented in the DOC file.
- Ability to convey a complete and engaging data story.
This assignment is estimated to take 30 to 35 hours, with a DOC file submission that should reflect a thoughtful approach to storyboarding and interactive design, ensuring that data-driven insights are both compelling and accessible.
Task Objective
The focus for this week is on leveraging advanced charting techniques and calculated fields within Tableau. You are to explore how advanced visualizations and calculated metrics can enhance the depth of analysis. The purpose of this task is to deepen your technical skills while simultaneously focusing on the clarity of the visual narrative.
Expected Deliverables
- A DOC file that outlines your approach to building advanced visualizations and integrating dynamic calculations.
- A detailed explanation of the newly applied calculated fields and their impact on the data analysis process.
Key Steps to Complete the Task
- Research and Selection: Study advanced visualization techniques and identify at least two methods (e.g., dual-axis charts, heat maps, etc.) that can be applied to a chosen dataset.
- Calculate and Integrate: Identify appropriate calculated fields and table calculations that can add value to your visualization. Document the rationale for each computation.
- Design and Diagram: Outline a detailed plan of how the advanced visualizations will be laid out and integrated within a dashboard context. Include a description of interaction between data points and text explanations supporting each calculation.
- Documentation: Prepare a comprehensive DOC file that includes detailed steps, design rationale, and the intended impact of the calculated fields on the overall visualization strategy.
Evaluation Criteria
- Innovative application of advanced charting techniques.
- Clarity and correctness of calculated field formulas and their documented impact.
- Quality and thoroughness of documentation in the DOC file.
- Overall technical depth and user-centered design approach.
This task is structured to demand 30 to 35 hours of work, with the DOC file serving as a detailed guide to your approach. The final document should clearly communicate both the technical aspects and the reasoning behind your design choices.
Task Objective
This week you will focus on optimizing your Tableau dashboard designs for performance, scalability, and enhanced user interactivity. The goal is to document methods for streamlining data processing and improving dashboard response times while ensuring interactive elements are intuitive and functional.
