This text approaches Statistical Sampling in the simplest possible way, including the theoretical contents and particularities of each Statistical Sampling scheme, dealing with probability sampling, non-probability sampling and mixed schemes, of much use nowadays. The authors try to make a book that does not move away from the theoretical aspects of SS, but we give much strength to the practical aspects and applications.
The users of this text range from university professors, people from different undergraduate programs, to aspiring Masters in the use of the techniques, so that their results have rigor and scientific validity.
We wish to clarify that this text is directed to Statistical or Probabilistic Sampling, not to Non Probabilistic Sampling; however, in Non Probabilistic Sampling, we tried to deepen what was possible, due to its magnitude, because of its importance in qualitative research, especially in Marketing.
