Data Storytelling

Dashboards that make data sing

Data without a story is just noise. The best analysts make the numbers talk.

🎯 Learning Objectives

  • Apply conditional formatting to highlight patterns in data
  • Design a one-page dashboard that communicates insight to a specific audience
  • Identify misleading data visualisation techniques

📚 Key Vocabulary

Conditional formatting
Automatic cell colour/style changes based on the cell's value
Dashboard
A visual summary of key data insights on one page for quick decisions
Data storytelling
Using visualisations to communicate a clear narrative from data
Truncated axis
A chart axis that doesn't start at zero — can make differences look bigger

Hook
5 mins

Show two charts of the same data — one with a y-axis starting at 0, one starting at a higher number to make a small change look dramatic. "This is used in politics, business and advertising every day."

  • Conditional formatting: colour scales, data bars, icon sets, custom rules
  • Sparklines: mini-charts inside a cell
  • Dashboard layout: summary stats at top, charts in the middle, detail below
  • Chart choice refresher: line (time), bar (comparison), scatter (relationship), pie (use sparingly)
  • Misleading techniques: truncated axes, cherry-picked dates, missing context

Dashboard challenge: students receive a "messy dataset" (school-themed: mock attendance, grades by subject, extracurricular participation — all fictional). Task: clean the data, apply conditional formatting to highlight outliers, create 3 meaningful charts, and build a one-page dashboard for "Senior Leaders" with a clear headline message. Export as PDF.

Share
5 mins

Data story share: each student states their dashboard's headline message in one sentence. Does the visual support it?

🔧 Tools & Resources

🤖 AI Angle

Use AI to suggest what type of chart is most appropriate for your data, or to write the interpretation paragraph — then verify the chart choice is correct.

📚 Homework

Find a data visualisation from a news article or report. Evaluate it: what does it show well? Is anything misleading? Screenshot and annotate.
