TLDR
Two different Bayesian approaches are explained and evaluated, one of which involves Bayesian model comparison (and uses Bayes factors) and the other assesses whether the null value falls among the most credible values.Abstract:
Psychologists have been trained to do data analysis by asking whether null values can be rejected. Is the difference between groups nonzero? Is choice accuracy not at chance level? These questions have been traditionally addressed by null hypothesis significance testing (NHST). NHST has deep problems that are solved by Bayesian data analysis. As psychologists transition to Bayesian data analysis, it is natural to ask how Bayesian analysis assesses null values. The article explains and evaluates two different Bayesian approaches. One method involves Bayesian model comparison (and uses Bayes factors). The second method involves Bayesian parameter estimation and assesses whether the null value falls among the most credible values. Which method to use depends on the specific question that the analyst wants to answer, but typically the estimation approach (not using Bayes factors) provides richer information than the model comparison approach.read more

Using Bayes to get the most out of non-significant results
TL;DR: It is argued Bayes factors allow theory to be linked to data in a way that overcomes the weaknesses of the other approaches, and provides a coherent approach to determining whether non-significant results support a null hypothesis over a theory, or whether the data are just insensitive.

Default Bayes factors for ANOVA designs
TL;DR: Bayes factors have been advocated as superior to pp-values for assessing statistical evidence in data as mentioned in this paper, and they have been widely used in the literature for assessing power law and skill acquisition.

Bayesian Estimation Supersedes the t Test
TL;DR: Bayesian estimation for 2 groups provides complete distributions of credible values for the effect size, group means and their difference, standard deviations and their Difference, and the normality of the data.

Bayesian T Tests for Accepting and Rejecting the Null Hypothesis
TL;DR: To facilitate use of the Bayes factor, an easy-to-use, Web-based program is provided that performs the necessary calculations and has better properties than other methods of inference that have been advocated in the psychological literature.
