A classification of major research methods used in academic research and social surveys.
Overview
Research Methods
Research methods are classified into two major paradigms: qualitative and quantitative research. Qualitative research uses linguistic data to deeply understand 'why' and 'how,' including methods such as interviews, observation, and case studies. Quantitative research uses numerical data to objectively measure 'how much' or 'how many,' including survey research, experiments, and statistical analysis. In recent years, mixed methods research that combines both approaches has gained attention.
