StatPlus
Userfriendly statistical software
With StatPlus, one gets a robust suite of statistics tools and graphical analysis methods that are easily accessed through a simple and straightforward interface. The range of possible applications of StatPlus v5 is virtually unlimited  sociology, financial analysis, biostatistics, economics, insurance industry, healthcare and clinical research, probability calculations for lotteries and gambling operations  to name just a few fields where the program is already being extensively used.
While StatPlus is a "heavyduty" professional statistical analysis tool, the interface is so simple that even people who have no knowledge of statistics are capable of processing data, provided they know how to use PC and clear instructions are given. This frees up intellectual resources for analyzing the results, rather than agonizing over who and how processed the data, and if any mistakes were made in the process.
