PSPP is a Free program for statistical analysis of sampled data. It is a replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions.
Statisticians, students and scientists find it an ideal tool for convenient and fast sample data analysis.
Further information can be found at the PSPP web site.
The installers below are created through MacPorts. GUI programs are in /Applications/MacPorts and command line in
/opt/pspp/bin/. I worked with the PSPP developers to fix any OS X-specific issues, ensuring PSPP for Mac runs as well as other platforms.
Beginning with OS X 10.9 Mavericks, it is strongly recommended you use MacPorts to install PSPP.
OS X 10.10 (x86_64): Please install through MacPorts.
OS X 10.9 (x86_64): Please install through MacPorts.
OS X 10.8 (x86_64): PSPP 0.8.4, rev 0
OS X 10.7 (x86_64): PSPP 0.8.4, rev 0
Mac OS X 10.6 (i386 x86_64): PSPP 0.8.4, rev 0
Mac OS X 10.5 (ppc i386): PSPP 0.8.4, rev 0
10.5 NOTE: you will need a newer X11 than the one provided by the system, either from MacPorts or XQuartz.
Please direct PSPP-specific questions to the appropriate mailing lists, namely PSPP user discussions and PSPP bug reports.
