jamovi – free, open source statistical software

jamovi is an advanced, free and open source real-time, statistical spreadsheet, providing a suite of common statistical methods such as descriptives, t-tests, ANOVAs, correlation matrices, proportion tests, contingency tables, and factor analysis.

The software offers a spreadsheet editor, and a range of statistical analyses. jamovi can provide R syntax for each analysis that is run, and additional analyses for the tool can be developed using the R language.

The jamovi project was founded to develop a free and open statistical platform which is intuitive to use, and can provide the latest developments in statistical methodology.

Features include:

  • Easy to use.
  • Complete suite of analyses for (not just) the social sciences; t-tests, ANOVAs, correlation and regression, non-parametric tests, contingency tables, reliability and factor analysis.
  • Data filtering – filter out rows that you don’t want included in your analysis. The filters in jamovi are build on top of jamovi’s computed variable formula system, which allows the building of arbitrarily complex formulas.
  • Fully functional spreadsheet.
  • R syntax compatibility. In “R Syntax mode”, jamovi produces equivalent R code for each analysis.
  • Modules to increase functionality. Modules include:
    • Rj – Editor to run R code inside Jamovi.
    • jpower – power analysis for common research designs.
    • GAMLj – General Analyses for Linear Models.
    • jAMM – Advanced meditation models.
    • jsq – Bayesian methods.
    • distrACTION – Quantiles and probabilities of continuous and discrete distributions.
    • and many more.
  • Multi-file import with support for CSV, R, SPSS, Stata, SAS, and JASP files.
  • Export to PDF, HTML, CSV, R object (.rds, .RData), SPSS sav, SAS 7bdat, SAS xpt, and Stata.
  • Undo/redo functionality.
  • Templates – special data sets that are analogous to script files in more traditional statistical environments. They are a way to specify data types, computations, filters, transforms, and analyses in advance.
  • Plot color palettes (including a print-ready gray-scale palette).
  • Produces nice APA formatted tables, and attractive plots.
  • Screenshot tool.
  • Cross-platform support – runs under Linux, macOS, and Windows.
