Preparing a presentation with data? Consider using your data to tell a story.
Storytelling with data is much more powerful than creating a PowerPoint deck with talking points.
My students often take this latter approach when asked to deliver project presentations, but this method tends to fall short. Here are some of the most common pitfalls:
I try to help students prepare by explaining the key elements required for an effective data presentation. Best practices include identifying the takeaway, contextualizing the findings, and presenting the key numbers. (Check out this webinar for more details on best practices.) Here's a great example of this focused approach:
To help my students avoid pitfalls, I provide a detailed rubric that lists the standards of assessment. (You can download the full rubric here.)
The criteria is based on these five questions:
1. Did the team select an interesting story to tell with the data as it related to the topic and audience?
A story should have a clear beginning, middle, and end. Questions are useful to guide the audience with answers as are takeaways that drive the narrative from introduction to conclusion.
2. Did the team select appropriate visualizations (chart types) to present the data?
Charts and graphs should clearly show the data without bias. The chart type should be familiar to the audience. Avoid overly-complex charts that look fancy but don't clearly show insights.
3. Did the team apply effective design principles to the charts to clearly present the data?
Charts should be devoid of extraneous non-data elements such as shadows, borders, and use of color for decoration.
4. Did the team apply effective design principles to the presentation?
Presentation decks should be designed to support the presentation rather than be the presentation. Text should be limited and the use of visuals should be emphasized. All text should be readable (at least 36-point font) for the audience.
5. Did the group present visualizations that worked together to tell a coherent story?
The visualizations used should progressively reveal the insights or trends. Each visualization should highlight a single and different takeaway.
I evaluate each question on a 20-point scale. If students meet the expectations, they earn full credit, which in this case is 20 points. There is a bonus category that encourages students to go above and beyond the expectation, and it is worth one additional point.
Here’s an example that shows how I assess students on their selection and use of data visualizations. With this rubric to help them prepare, students can strive to exceed expectations while applying the recommendations included in the bonus category for extra points.
This may be a rubric for students, but it can prove useful for anyone presenting their data findings. Use the rubric as a checklist to help craft effective data presentations. And share your findings in a way that keeps your audience engaged and listening.
