Gratis Spss 17 Free For Windows 7 32 Bit [UPD]
I have been working with SPSS and PSPP, the results are basically the same. PSPP just still misses some functions. However currently pspp added factor analysis and reliability analysis. I prefer using pspp because it is free (open source!!) software and is much faster than spss.
