A Simple Game with student choices in Confidence Intervals

Sign up or log in to save this to your schedule, view media, leave feedback and see who's attending!

Students in introductory statistics courses learn how margins of error for confidence intervals are affected by the choices of sample size, confidence level, and inherent variability in the population. The end result is often the assertion that larger sample sizes are superior and can make a margin of error suitably small, at the level of a researcher’s specification. However, this often ignores the reality that increasing the sample size costs time and money for most research projects.
To help students understand and balance the choices between increasing sample size and/or changing the confidence level for an interval, we setup a simple extra credit game to help them think more deeply about these issues where the incentives for the game are aligned with realistic choices faced by someone conducting real research.
