GNU PSPP is a program for statistical analysis of sampled data. It is a Free replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions. The most important of these exceptions are, that there are no “time bombs”; your copy of PSPP will not “expire” or deliberately stop working in the future. Neither are there any artificial limits on the number of cases or variables which you can use. There are no additional packages to purchase in order to get “advanced” functions; all functionality that PSPP currently supports is in the core package. PSPP is a stable and reliable application. A brief list of some of the PSPP's features follows below. Support for over 1 billion cases. PSPP is particularly aimed at statisticians, social scientists and students requiring fast convenient analysis of sampled data. Downloading PSPP As with most GNU software, PSPP can be found on the main GNU ftp server: (via HTTP) and (via FTP). Documentation Further information

For business applications where questions might be simpler and precision not as necessary, Excel may be just fine.
