The correct options are: "quantitative analysis - qualitative analysis"
Qualitative research or methodology is the type of linguistic-semiotic based research method used mainly in the social sciences, and all those other than the survey and the experiment are considered qualitative techniques. That is, open interviews, discussion groups or observation techniques and participant observation. The qualitative research collects the complete discourses of the subjects to proceed then to their interpretation, analyzing the relationships of meaning that occur in a certain culture or ideology.
Quantitative research assigns numerical values to the statements or observations, with the purpose of studying with statistical methods possible relationships between the variables and generalizing the results to a given population through sampling techniques. On the contrary, qualitative research does not insist on representation. It tackles its problems of external validity through various strategies, including prolonged stay in the field, the triangulation of results or the adoption of structural representation: include in the sample members of the main elements of the social structure around the phenomenon study.
