StatPlus 2007 4.8.0.0

With StatPlus 2007, one gets a robust suite of statistics tools and graphical analysis methods that are easily accessed though a simple and straightforward interface. The range of possible applications of StatPlus 2007 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 2007 is a "heavy-duty" 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 urces for analyzing the results, rather than agonizing over who and how processed the data, and if any mistakes were made in the process.
