The Bayes factor assisted you in optimal guesswork: how much you should, subjectively, favor one hypothesis over the other, in light of the available evidence.

A Bayesian analysis of the data from a simple experimental design is straightforward. Recall that the theorem implies that the posterior is the likelihood weighted by the prior…
