Question 1 of 5
Surveys & Standardized Questionnaires (SUS, SUPR-Q, UEQ)
A team administers SUS to 8 participants and gets a score of 74. What is the most important caveat to communicate when reporting this result?
SUS scores above 68 are always statistically reliable regardless of sample size
The confidence interval with n=8 is roughly ±15 points, making the number imprecise for benchmarking
SUS requires at least 100 participants to be a valid instrument
A score of 74 is below average and the team should stop the study
