Qualitative research in sociology is the study and analysis of theoretical facts about human beings and their social and environmental surroundings. It is carried out based on qualities or factors that cannot be expressed in numerical terms but can only be explained. For example, the study of beliefs, behaviors, and relationships can be called qualitative research. It is also known as field research, as the process requires direct inspection, observation, and interaction. Quantitative research is based on collecting and studying numerical or quantifiable data about people or groups. These are things that can be measured and expressed in numerical terms. Aspects such as gender, practices, professions, and opinions are some examples of factors considered for quantitative studies. Surveys of different types like population surveys or marketing surveys are the best examples of quantitative research.
