User research helps product teams understand their users’ goals, needs, and behaviors. It guides better decisions throughout the product lifecycle from early discovery to post-launch evaluation.
Different types of research answer different kinds of questions. Some methods explore what people want or feel, others observe how they behave. By selecting the right approach, teams can reduce uncertainty, improve usability, and design products that solve real problems.
Research methods fall into four main categories based on the type of data, the nature of insights, the research setting, and the intended purpose.
Qualitative vs. Quantitative
This distinction relates to the type of data collected and how it’s interpreted.
Qualitative research focuses on meaning and understanding. It reveals why users behave in certain ways, what motivates them, and how they experience a product. Interviews, diary studies, and field observations are common methods. These help teams uncover patterns and pain points that aren’t always visible in metrics.
Quantitative research focuses on measurement and scale. It answers questions like how many, how often, and what percentage. Surveys, usage analytics, A/B testing, and structured usability studies fall into this category. These methods are useful for tracking patterns, validating assumptions, and comparing results over time.
While qualitative research is best for exploring ideas and finding root causes, quantitative research helps teams prioritize and scale with confidence. Together, they provide a fuller picture.
