Question 1 of 5
User Interviews
A product team wants to know whether their redesigned checkout flow is faster than the original. They plan to run 5 user interviews to answer this question. What is wrong with this approach?
Interviews are the wrong method — comparative performance questions require a usability test or A/B experiment, and 5 participants is too small a sample for statistically reliable data
Nothing is wrong — 5 users is the standard sample size and interviews surface all types of insight
The sample size is fine, but interviews should be replaced with a survey to get quantitative data
Interviews are fine for this question, but the team should recruit 40+ participants to reach statistical significance
