Bayesian data analysis methods have become more mainstream in recent years, in part due to the availability of user friendly statistics packages that implement Bayesian versions of standard analyses: ANOVA, regression, etc. While tools such as R, WinBUGS, JAGS and Stan are indispensible to Bayesian statisticians, simpler tools such as JASP provide a gentler introduction to Bayesian data analysis! This tutorial (and page!) is a work in progress, but the intention is to provide an introduction that is suitable to psychology students without any previous knowledge of Bayesian methods.
