Qualitative research aims to gather an in-depth understanding of human behavior and reasons for behavior through methods like interviews, focus groups, observation, and analysis of diaries, journals, and other materials. It enables complex experiences to be studied and individuals to be examined more deeply, though the data can be time-consuming to analyze and less generalizable than quantitative research. Qualitative research seeks meaning, experiences, situations, exploration of ideas, interpretation of meanings, and explanation of complex processes.
