Understanding Sample Size in UX Research

How many participants do you need to test in order to make valid research claims? In this episode, we dive deep into the science and psychology behind sample sizes in user testing. Whether you're working with five users or five hundred, the number you choose can shape the story your research tells—and how credible your findings appear to stakeholders.

• Why sample size is one of the most misunderstood elements in product research
• The psychological impact of “too few” vs. “just enough” users in high-stakes design reviews
