An Overview of Statistical Data Analysis

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.
