About PSPP GNU PSPP is a program for statistical analysis of data. It is a free replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions. It has the data and variable view tabs, and has a layout that is almost identical to SPSS. Its option and output windows also look very similar to SPSS’s. Important advantage of PSPP over SPSS is that it can work in both windows as well as linux platforms. Go to website https://www.gnu.org/software/pspp/ for more information.
