What type of research focuses on understanding users' needs through observations and interviews?

Qualitative research is designed to gain in-depth insights into human behavior, motivations, and experiences. By emphasizing observations and interviews, this type of research allows designers and researchers to capture the nuances of user experiences, preferences, and emotions. The rich, descriptive data that emerges from qualitative methods helps to form a more comprehensive understanding of the context in which users interact with products or services. This understanding is essential for creating user-centered designs that address their specific needs and challenges.

In contrast, quantitative research primarily focuses on numbers and statistical analysis to test hypotheses and measure user behavior or attitudes, often through surveys or experiments. Secondary research involves analyzing existing data or research studies rather than gathering new data directly from users. Pseudoscientific research lacks the rigorous methodological framework and scientific validity, making it an unreliable source for understanding user needs. Thus, qualitative research stands out as the most appropriate method for exploring and understanding users' needs through direct interactions and observations.
