Data Storytelling Group Project · Guideline
Turn a focused analytical question into a clear, evidence-based story
Project at a glance
- Each group will deliver a 10-minute presentation, followed by a 1–2 minute Q&A.
- Presentation order will be determined by a random draw.
- Every group member must contribute meaningfully and participate in the presentation.
- If multiple groups choose the same topic, they may be scheduled in different sessions to reduce repetition.
Choose a topic
Start with the Group Project Topics catalog. Each topic page introduces the available data, important variables, possible questions, and a sensible first step.
The catalog is a set of starting points—not a list of required questions. Your group should narrow the topic into a focused question and develop its own evidence-based story.
Your group may use another dataset with advance approval. Send the instructor the proposed data source and a short explanation of the question you want to investigate. Also submit any additional dataset that you combine with a suggested topic.
Build the data story
1. Frame the question
- Give the audience enough background to understand why the topic matters.
- State one focused project interest, problem, or question.
- Identify the audience and the decision, action, or understanding your story should support.
2. Prepare and examine the data
- Explain the observations and variables you selected.
- Document important filtering, recoding, joins, and missing-data decisions.
- Use descriptive statistics to establish context and identify meaningful patterns.
- Verify row counts and key assumptions after major transformations.
3. Visualize the evidence
- Use charts that match the analytical question and data type.
- Make labels, units, legends, and comparison groups easy to understand.
- Use color intentionally and choose a color-blind-friendly palette.
- Remove visual elements that do not support the message.
4. Shape the narrative
A strong presentation usually follows this sequence:
- Context — What should the audience know?
- Question — What did your group investigate?
- Evidence — What patterns did the analysis reveal?
- Meaning — Why do those patterns matter?
- Takeaway — What should the audience remember or do next?
5. Explain significance and limits
- Connect the findings to a practical, organizational, social, or policy context.
- Distinguish association from causation.
- Acknowledge relevant limitations, missing information, and uncertainty.
Deliverables
Presentation slides
- Keep slides readable, visually consistent, and focused on one point at a time.
- Include descriptive statistics and
ggplot2visualizations that directly support the story. - Other visual aids are welcome when they improve understanding.
- Cite data sources and external material consistently.
Reproducible R script
- Organize the script with section headers and explanatory comments.
- Include every import, transformation, summary, and visualization needed to reproduce the presentation.
- Explain techniques not covered in class.
- Make sure the script runs from beginning to end without errors.
Submission instructions and presentation dates will be posted in Brightspace for each section.
Evaluation rubric
| Dimension | Evidence of strong work |
|---|---|
| Data transformation and descriptive statistics | Accurate, purposeful preparation and summaries that support the question |
| Data visualization | Clear, honest, well-labeled charts that reveal meaningful comparisons or trends |
| Data storytelling | A focused narrative that connects context, evidence, meaning, and takeaway |
| Slides and visual materials | Readable, polished, consistent, and appropriate for the audience |
| Group presentation | Coordinated delivery, balanced participation, clear explanations, and effective Q&A |
| Code quality | Reproducible, organized, documented, and error-free R code |
Practical advice
- You do not need to analyze every available variable.
- Begin broadly, then narrow the analysis to the evidence that strengthens the story.
- Treat exploration as iterative: summarize, visualize, question, refine, and verify.
- Prefer a few well-explained findings over many disconnected charts.
- Ask for help early when your ideal data structure or transformation path is unclear.
Collaboration and peer evaluation
- Address collaboration concerns early and communicate them to the instructor while there is time to resolve them.
- Each student will evaluate other groups’ presentations using the provided peer-evaluation form.
- Brightspace will contain the submission procedure and grading details.
