PSPP overview

GNU PSPP is a program for statistical analysis of sampled data. It is a free as in freedom replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions

The most important of these exceptions are, that there are no "time bombs"; your copy of PSPP will not "expire" or deliberately stop working in the future. Neither are there any artificial limits on the number of cases or variables which you can use. There are no additional packages to purchase in order to get "advanced" functions; all functionality that PSPP currently supports is in the core package

PSPP is a stable and reliable application. It can perform descriptive statistics, T-tests, anova, linear and logistic regression, measures of association, cluster analysis, reliability and factor analysis, non-parametric tests and more. Its backend is designed to perform its analyses as fast as possible, regardless of the size of the input data. You can use PSPP with its graphical interface or the more traditional syntax commands

A brief list of some of the PSPP's features follows below. We also made available a page with screenshots and sample output. PSPP has:

  • Support for over 1 billion cases
  • Support for over 1 billion variables
  • Syntax and data files which are compatible with those of SPSS
  • A choice of terminal or graphical user interface
  • A choice of text, postscript, pdf, opendocument or html output formats
  • Inter-operability with Gnumeric, LibreOffice, OpenOffice.Org and other free software
  • Easy data import from spreadsheets, text files and database sources
  • The capability to open, analyse and edit two or more datasets concurrently. They can also be merged, joined or concatenated
  • A user interface supporting all common character sets and which has been translated to multiple languages
  • Fast statistical procedures, even on very large data sets
  • No license fees
  • No expiration period
  • No unethical "end user license agreements"
  • A fully indexed user manual
  • Freedom ensured; It is licensed under the GPLv3 or later

What’s new in version 1.6.0-1

Updated on Jun 17 2022

  • An error in the displayed signficance of oneway anova contrasts tests has been corrected.
  • Added Drag-N-Drop in output view.
  • The Explore GUI dialog supports the "Plots" subdialog. Boxplots, Q-Q Plots and Spreadlevel plots are now also available via the GUI.
