Question 1 of 5
Standardized Usability Surveys: SUS, UMUX-Lite & SEQ
A UX researcher administers SUS to 12 participants and reports a mean score of 74. What is the most critical problem with presenting this as a benchmark?
SUS requires a minimum of 100 participants to be statistically valid in any context
With only 12 participants the confidence interval is roughly plus or minus 20 points, making the score too imprecise to use as a benchmark
SUS scores cannot be compared to industry norms unless the study uses a between-subjects design
A score of 74 falls below the average SUS benchmark of 78 and should not be reported
