UX Psychology 79 implied HN points 02 Aug 22
  1. The number of participants in a usability study should be chosen based on factors like the impact of the study, complexity of the product, target user groups, and study's purpose. A range of 3-20 participants is generally valid, with 5-10 being a sensible baseline.
