                   -Deduction
                   -Induction
                   -Abduction

Qualitative and quantitative research

Qualitative research is a method of inquiry employed in many different academic disciplines.

Qualitative researchers may use different approaches in collecting data, such as the grounded theory practice, narratology, storytelling, classical ethnography, or shadowing. Qualitative methods are also loosely present in other methodological approaches, such as action research or actor-network theory.

Quantitative research refers to the systematic empirical investigation of social phenomena via statistical, mathematical or computational techniques.

Quantitative research is used widely in social sciences such as psychology, economics,sociology, and political science, and less frequently in anthropology and history. Research inmathematical sciences such as physics is also 'quantitative' by definition, though this use of the term differs in context.

Qualitative psychological research methods include interviews, firsthand observation, and participant observation.

Quantitave psychological research metods lends itself to the statistical testing of hypoteses.
