Superiority testing assesses whether the final power of a study is in agreement with the power as stated in the protocol of the study. This chapter shows how superiority can be assessed.

However, this does not work, because generally the values higher and lower than the averages tend to even out, and the results would be zero. A pragmatic solution was taken by statisticians around the world. They decided to
