Innocent Until Proven Guilty
Case, Catherine; Whitaker, Douglas
Mathematics Teacher, v109 n9 p686-692 May 2016
In the criminal justice system, defendants accused of a crime are presumed innocent until proven guilty. Statistical inference in any context is built on an analogous principle: The null hypothesis--often a hypothesis of "no difference" or "no effect"--is presumed true unless there is sufficient evidence against it. In this article the authors present an activity where students use simulations--with physical spinners and a computer applet--to introduce and explore the concept of statistical power.
