  The use of statistical software in academia and enterprises has been evolving
over the last years. More often than not, students, professors, workers, and
users, in general, have all had, at some point, exposure to statistical
software. Sometimes, difficulties are felt when dealing with such type of
software. Very few persons have theoretical knowledge to clearly understand
software configurations or settings, and sometimes even the presented results.
Very often, the users are required by academies or enterprises to present
reports, without the time to explore or understand the results or tasks
required to do an optimal preparation of data or software settings. In this
work, we present a statistical overview of some theoretical concepts, to
provide fast access to some concepts.
