About PSPP for Mac
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.
