BioStat is the first user-friendly biology and medicine oriented professional statistical application.

With BioStat, one gets a robust suite of statistics tools and graphical analysis methods that are easily accessed though a simple and straightforward interface.

While BioStat is a "heavy-duty" biology and medicine oriented 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.
