PSPP is a free program for statistical analysis of sampled data.  It is similar to SPSS with a few exceptions. PSPP is particularly aimed at statisticians, social scientists and students requiring fast convenient analysis of sampled data.

Windows installation

Pre-compiled PSPP installers are not available on the PSPP web site.  However, they are available from third-party sites.  To find a third-party download site, go to the PSPP web site, look for the Binaries section, and click the Download link for Windows. This will take you to a page with links to third-party sites.  Be sure to download the full version.  Then simply unzip the executable file and run it.

Mac installation

Since there are no third-party web sites with pre-compiled versions of PSPP for Mac, we have created an installer for the OS X 10.5 and 10.6 operating systems. Currently, we do not have installers for OS X 10.4 or earlier.  These were created using MacPorts.

Step 1: Verify system requirements

  • OS X 10.5 (ppc,i386) or 10.6 (i386,x86_64)
  • X11 is installed

Step 2: Download the disk image (~140MB)


Step 3: Run the installer and launch PSPP

  1. Mount the disk image.
  2. Open the disk image, and double-click the pspp-0.6.2.mpkg or pspp-0.7.8.mpkg file.
  3. Run the installer.
  4. After installation, try launching the application in one of the following ways:
    • Double-click the pspp application, located inside /Applications/MacPorts/.
    • In Terminal run /opt/local/bin/pspp or /opt/local/bin/psppire.
  5. It is helpful to make an alias by simply placing it in the dock .
