GNU PSPP vs jamovi

GNU PSPP is free desktop software for statistical analysis of sampled data and a free replacement for SPSS. It provides graphical and command-line interfaces, scripting support, statistical tests, and regression models. Analyses include descriptive statistics, t-tests, ANOVA, linear and logistic regression, cluster analysis, reliability and factor analysis, and non-parametric tests. Data can come from PSPP system or portable files, Gnumeric, ODS, PostgreSQL, and TXT or other delimited text. Results can be written as text, PostScript, PDF, OpenDocument, or HTML. PSPP syntax and data files are compatible with SPSS, with a stated aim of producing similar results. The project lists interoperability with Gnumeric, LibreOffice, OpenOffice.org, and other free software. It supports Linux, macOS, and Windows as desktop platforms. The GNU GPL version 3 or later governs the software. Its listed plan is free, with no license fees or artificial limits on cases or variables.

jamovi is a free, open-source statistical analysis program for working with data through point-and-click controls or scripting. It supports statistical tests, regression models, and Bayesian analysis, and imports SPSS (.sav), SAS, Stata, CSV, and Excel files. The spreadsheet-style interface lets users choose variables and settings, with results updating as they work; analysis does not require writing code. The desktop application runs on Windows, macOS, and Linux, and works offline after installation. Cloud access runs in a browser without installation or setup, including on modern browsers, Chromebooks, lab computers, tablets, and other devices. The free Cloud Guest plan requires no credit card, but guest sessions lack queue skipping, unlimited session length, longer idle timeouts, and larger datasets. jamovi is powered by R and displays the R syntax behind analyses. Data, analyses, and results can be saved together in a shareable, reproducible file. Cloud can connect to OneDrive to open and save jamovi files; Cloud plans include the full module library.
