JASP

JASP is a free, open-source statistical analysis program developed at the University of Amsterdam. Designed with a spreadsheet-style interface, it aims to provide a user-friendly way to perform statistics, building upon the R programming language.

The software supports both frequentist and Bayesian analyses, including t-tests, ANOVA, regression, mixed models, factor analysis, and meta-analysis. It is extensible via a module system that covers specialized areas such as machine learning, structural equation modeling, network analysis, audit, robust statistics, and distributions.

By providing publication-ready output and emphasizing the open scientific method, JASP focuses on ensuring free access to analysis tools for researchers.
