Abstract: 

Statistical power is defined as the likelihood that a particular test will correctly determine a false null hypothesis. This paper describes an ongoing research program focused on the teaching, learning, and understanding of ideas related to statistical power. The research described includes investigations of the effectiveness of instruction using a specially designed interactive software program (the Power Simulator), and the development and use of assessment instruments to measure students' informal understandings of power prior to instruction.

The CAUSE Research Group is supported in part by a member initiative grant from the American Statistical Association’s Section on Statistics and Data Science Education
