Skew The Script: A Website Offering Socially Relevant Math Lessons
Skew The Script lessons identify misleading data arguments and show students how the tools of statistics can be used to gain a deeper understanding of some of our country’s longstanding problems. Even more important, the lessons provide students from widely differing backgrounds with a common analytical lens (rigorous data analysis) for heightened discourse around social issues.
