Who is this presentation for?

  • Data scientists, data analysts, and data visualizers

Prerequisite knowledge

  • A basic understanding of how business metrics and analytics are communicated, both internally and externally

What you'll learn

  • Learn how to use the science of human perception to improve the way you communicate data


You likely already use business metrics and analytics to achieve success in your data-driven organization and visualize, communicate, and explain your findings to drive decisions and results. The better you’re able to do this, the bigger the competitive advantage you and your organization will have. But are you communicating and visualizing in the most effective way possible?

Sebastian Gutierrez demonstrates how to use the science of human perception to drastically improve your data visualizations, reports, and dashboards, covering best practices, strategies, and techniques.

Topics include:

  • How to correctly use reference points so that human biases don’t distort your data
  • How to chose data representations that show contrast versus trends
  • How to correctly communicate perception of change and proportion
  • How memory of a visualization distorts the actual chart and what to do about it
  • How symmetry, linearity, and number of data points distort understanding and how to fix it
  • How size of scales and data plotted change perception of correlations
  • How to best communicate correlations for effective understanding and memory
