How is the sample delimited and designed? The first step is the selection of the sample type:

The characteristics of the population must be limited and the units of analysis must be differentiated, which are established from individuals (simple unit) or from organizations, families, groups, newspapers, etc. (collective unit). Once the unit of analysis has been delimited, the population that will be studied and whose results will be generalized will be delimited. The unit of analysis can be a news story, a paragraph, a piece of music…

Samples can be:

               Probabilistic samples

                   Simple random samples

                   Systematic random samples

                   Stratified samples

                   Aggregated samples

   Non-probabilistic samples

                   Convenience samples

                   Strategic samples
