The official web site for PSPP is GNU PSPP. Before downloading, it's worthwhile to browse the official site and learn more about PSPP.
When you're ready to try it, the next step is to install it on your own computer. There is no online or cloud version.
PSPP can be downloaded for free from the Free Software Foundation. The Obtaining GNU PSPP page has links to various download locations.
The download page has multiple versions to choose from. The recommended version for beginners is the "release" version. The development versions are actively being built and are less reliable.
Choose the installation software that is appropriate for your computer's operating system. Windows users should try the versions available at the "latest release" link. Mac users should look at the "application bundle."
The download page also has source code: computer programming instructions that are used to create the software. Most students will not need the source code.
Use the typical software installation methods for your computer to installed the downloaded file. On Windows and Macs, this is typically double-clicking to run the program. Follow the guidance from the installation steps.
Administrative privileges may be needed on some computers to install software. MacOS, in particular, may balk at running the installation software because it comes from an unknown or unsigned source. This reluctance to install unsigned software is a safety feature. The solution is to give the installation application permission to run, even though it is from an unsigned source. This support article from Apple explains how to give this permission.
PSPP cannot be installed on ChromeOS devices (Chromebooks and Chromeboxes) because there is no web-based version of the software. ChromeOS is limited to running web-based applications.
Some inexpensive Windows PCs may not allow installation of downloads from the official PSPP web sites. The problem is that these machines can only install software from the Microsoft Store. Check the Micsoft Store online to see if PSPP is available.
