About the course

Numbers don’t take a position—they’re just information for us to interpret. This course helps you develop a healthy skepticism for how data is presented and examines how it’s often purposefully distorted or inadvertently misinterpreted. We will develop a framework for understanding common misinformation around the theme of modern data science. Using real-life examples, we will learn specific tools to understand what questions we should be asking of data in order to spot the lies, damned lies, and statistics (with a little fake news thrown in for good measure.)


  • Develop a framework for critically evaluating data-based claims
  • How data analytics can lead to incorrect conclusions
  • Tools for asking the right questions of data


  • Quickly identify opportunities or risks when presented with new reports, studies, analytics, and techniques
  • Better determine what type of information to extract from data by asking better questions
  • Defend against poor decision making due to misrepresented information
