Framework
The four dimensions of user research methods

Every user research method sits somewhere on four dimensions: qualitative or quantitative, generative or evaluative, attitudinal or behavioral, and moderated or unmoderated. This card explains each pair in a line, so a team can see why an interview, a survey and a usability test give such different answers. Use it when choosing or mixing methods for a study. Koji's AI interviews are moderated and qualitative, with structured questions for numbers.
Where this appears
What's in this framework
- Qualitative vs quantitative: Qualitative answers why and how, through interviews and observation. Quantitative answers how many and how often.
- Generative vs evaluative: Generative finds the problem and the users before you decide what to build. Evaluative tests whether a solution works.
- Attitudinal vs behavioral: Attitudinal captures what people say. Behavioral captures what they do, which often differs from what they said.
- Moderated vs unmoderated: Moderated has a researcher guiding in real time, good for probing. Unmoderated scales at lower cost but misses nuance.
