Summary
In the previous chapters, and in Chapters 4 and 6 in particular, we already encountered methods for testing hypotheses. We used these statistical tests to determine if a given empirical correlation corresponds to the real key, or to an incorrect key. This chapter takes a more systematic look at statistical testing and derives methods that are—in some particular sense—best possible.
