Answering "What are the differences between qualitative and quantitative research methods?" v There are differences between the two research methods: Quantitative Research and Qualitative Research. Quantitative research uses deductive process as the study approach, investigates phenomena that lend themselves to precise measurement and quantification, often involving a rigorous and controlled design; it's more on objective and reductionist, most closely allied with the positivist tradition. Qualitative research, on the other hand, which is most often associated with naturalistic inquiry with inductive study approach, investigates phenomena through the collection of rich narrative materials using a flexible research design, broad, subjective and holistic. The researchers' expectations in quantitative research are to test and verify hypothesis and theories, and predict physical or human events; role of the person being studied is the subject, its behavior as a means to the end. While in qualitative data - researchers' expectations are to discover information, to describe human experiences, to develop concepts and theories, and to explain and interpret human behavior or events; person being studied is an active participant and its behavior is both means and end. In addition, Data being collected in qualitative research reflects the perceptions of persons being studied in form of "words" for individual interpretation, and is collected throughout the study through unstructured interviews and observations in settings natural to person being studied with no manipulation of the environment by the researcher. On the contrary, quantitative data is independent on perceptions of person being studied in form of "numbers" for statistical analysis, and is collected in designated time frame through structured interviews, questionnaires, observations, scales, or physiologic instruments with controlled environment and researchers manipulates the environment to control for variables. Lastly, quantitative findings are generalized, accept or reject theoretical propositions with numerical accounts of data that are highly reliable. While qualitative findings are unique, dynamic, understands phenomena and new theory with written descriptions of findings that are highly valid.
