Figure 1

A figure showing how Bayes factor will change according to different observed effects. The red left vertical line represents the null hypothesis (an effect of null), and the right green vertical line represents an alternative hypothesis to the null hypothesis with an effect of 1.0. The black curve shows that Bayes factor will be 1.0 when the observed effect size is exactly half of the effect size of the alternative hypothesis; and the curve shows that Bayes factor will decrease with increasing observed effect sizes.
