Qualitative research is often used in the social sciences to collect, compare and interpret information, has a linguistic-semiotic basis and is used in techniques such as discourse analysis, interviews, surveys, records and participant observations
Quantitative research study delves into a phenomenon through quantitative data collection and using mathematical, statistical and computeraided tools to measure them.
