GNU PSPP is a free replacement for SPSS that reads and writes SPSS .sav files and understands much of the SPSS syntax language. It has both a graphical interface and a command line, and covers descriptive statistics, t-tests, ANOVA, regression, factor analysis and non-parametric tests.

Who it suits

  • PSPP says it is “particularly aimed at statisticians, social scientists and students requiring fast convenient analysis of sampled data.”
  • You can use it through a graphical interface or with SPSS-style syntax commands.

Switching from SPSS

Your data: SPSS data files: .sav, .zsav, .por. GNU PSPP opens .sav, according to its own documentation.

  1. Keep your data from SPSS as a .sav (or .zsav / .por) file.
  2. Open that file in GNU PSPP.

Watch out for:

  • Data files compatible with SPSS; GET DATA also reads Gnumeric and OpenDocument spreadsheets, text files and PostgreSQL.
