PSPP is a free software application for analysis of sampled data. It has a graphical user interface and conventional command line interface. It is written in C, uses GNU Scientific Library for its mathematical routines, and plotutils for generating graphs.
It is intended as a free replacement of the proprietary program SPSS.

Features
PSPP can import Gnumeric, OpenDocument and Excel spreadsheets, Postgres databases, comma-separated values- and ASCII-files. It can export files in the SPSS 'portable' and 'system' file formats and to ASCII files. It can perform T-tests, ANOVA, linear regression and a variety of other statistical operations. It also has extensive facilities for recoding, rearranging and manipulating data.
The PSPP project (originally called "Fiasco") is a free, open-source alternative to the proprietary statistics package SPSS. SPSS is closed-source and includes a restrictive licence and digital rights management, allowing use of the program for only a limited period before renewing the licence. The author of PSPP considered this ethically unacceptable, and decided to write a program which would be functionally identical to SPSS, except that there would be no licence expiry, and everyone would be permitted to copy, modify and share the program.

Third Party Reviews
In the book "SPSS For Dummies", the author discusses PSPP under the heading of "Ten Useful Things You Can Find on the Internet" [1]. In 2006, the South African Statistical Association presented a conference which included an analysis of how PSPP can be used as a free replacement to SPSS [2].
