Bayesian tools for design and user research.
Say what a small study can and cannot support: how many problems remain unseen, whether raters agree, and what to ask next.
Questions these tools answer
- We found these problems with five users. How many are we missing?
- Do our reviewers agree beyond chance?
- Which question would best tell our explanations apart?
- How sure are we of a rate, given what the team believes beforehand?
