Top Tips for Communicating Data for Better Decisions

Understanding Data

  1. Start data analysis with a policy question and challenge your assumptions: Effective analysis begins with a clear understanding of the issue or decision at hand. Our perceptions do not always align with reality. Data helps us challenge intuition and make more informed decisions.
  2. Always provide context for percentages: Percentages alone can be misleading. Presenting both relative and absolute values helps convey the true scale of an issue.
  3. Distinguish correlation from causation: Just because two things happen together does not mean one causes the other. Consider alternative explanations and look for stronger evidence before drawing conclusions.
  4. Be transparent about uncertainty: Estimated data contains some level of uncertainty. Acknowledging margins of error or confidence intervals strengthens credibility and supports more accurate interpretation.

Data Visualization and Communication

  1. Use visuals to explain complexity: Clear, well-designed charts and graphics help audiences quickly identify patterns, trends, and outliers that may not be evident in raw numbers.
  2. Choose the right visual: Different charts serve different purposes. For example, line charts are effective for showing trends over time, while bar charts are better suited for comparisons.
  3. Keep visuals simple: Avoid unnecessary labels, colours, gridlines, or decorative elements that can distract from the key message. Simpler visuals are often more effective. Colour should guide attention and highlight key insights, not overwhelm the audience.
  4. Use maps carefully and sparingly: Maps can be powerful tools, but poor design may mislead or exaggerate differences. Use maps only when geography is central to the message.

From Insight to Action

  1. Focus on action: Data is most valuable when it informs decisions. Its ultimate purpose is to support better policies, stronger programmes, and more effective decisions. Don’t forget to give prominence to the key insight to inspire action.
