By Joseph G. Eisenhauer Misinterpretation of regression results—particularly confusion between correlation, causation, and predictive power—remains a challenge in statistics education. This paper introduces the “perfect” regression as a pedagogical device for illustrating spurious correlation and overfitting. Using extreme cases with small samples and randomly generated … [Read more...] about The ‘Perfect’ Regression: A Device for Demonstrating Spuriousness and Overfitting

A Sampling Activity to Anchor Big Statistical Ideas
By Sandra Madden, University of Massachusetts - Amherst Have you ever gone looking for a highly productive and foolproof statistical reasoning task? In 2006, I designed a statistical sampling task for use in a professional development project. The intention was to showcase important statistical ideas, encourage conjecture and statistical argument, and illustrate the … [Read more...] about A Sampling Activity to Anchor Big Statistical Ideas
