One important benefit of Bayesian statistics is that you can provide relative support for the null hypothesis. When the null hypothesis is true, p -values will forever randomly wander between 0 and 1, but a Bayes factor has consistency (Rouder, Speckman, Sun, Morey, & Iverson, 2009) , which means that as the sample size increases, the Bayes Factor will tell you which of two hypotheses has received more support. Bayes Factors can express relative evidence for the null hypothesis (H0) compared to
