The use of qualitative research is used to gain a deeper understanding of the human experience and behavior. Qualitative data is gathered through non-numerical methods such as observations, interviews and survey responses. In fields like sociology, education, psychology and anthropology qualitative research is commonly used.
Quantitative research is used for testing hypotheses, and to quantitate data. Quantitative methods of research rely heavily on numerical data such as surveys and statistics. Quantitative analysis is used in many fields, including economics and medicine.
Authors choose the specific method of research and design based on their research question, nature of data collected and study goals. The qualitative method is used to explore complex phenomena, gain a better understanding of people’s behavior and experience and understand them in depth. Quantitative studies are often used to test hypotheses or quantify data.
Depending on the specific questions that are being addressed, the types of data that will be collected, and what the goal of the study is, authors choose the best research design. In qualitative research, ethnography, grounded theories, and case studies are some of the most common designs. In quantitative research, common designs include observational studies, experimental designs and quasi-experimental ones.
The choice of a research design is generally based on what questions are being asked, and the types of data that will be collected. Researchers must carefully evaluate the advantages and disadvantages of different research designs and select the most appropriate one for their particular research goals.
