The way statistics is used (and maybe even perceived) in psychology has drastically changed over the last few years – computationally as well as methodologically. From a computational perspective, up to some years ago many psychologists considered R as an analysis tool used by the nerdiest quants only. In recent years, R has taken the field of psychology by storm, to the point that it can now safely be considered the lingua franca for statistical data analysis in psychology. R is open source, makes statistical analyses reproducible, and comes with a vast amount of statistical methodology implemented in a myriad of packages. Speaking of packages, in the past decade a flourishing psychometric developer community has evolved; their work has made R a powerful engine for performing all sorts of psychometric analyses. From a methodological perspective, the latent continuum of statistical methods in modern psychology ranges from old school classical test theory approaches to funky sta
