Our purpose was to introduce and explore a dynamic and interactive way of teaching a complex concept in statistics. Our research has used small sample sizes and single class presentations. The findings are far from definitive and conclusive. Future research needs to contrast the use of Power Simulator with instruction where the software is not used. This would be informative for comparison of both classroom presentations and out-of-class assignments. As for now, the results suggest that Power Simulator povides an effective way to introduce students to the complex concept of statistical power analysis. We are encouraged by the results to continue development of the program and find new ways to incorporate the methodology into statistics instruction.
