A user experience reseаrcher cоnducted а study tо cоmpаre the usability of two different website designs (Design A and Design B). The researcher collected data on five usability metrics: task completion time, error rate, user satisfaction, ease of use, and visual appeal. To compare the two designs on each metric, the researcher conducted separate independent samples t-tests with a significance level of 0.05 for each test. The results showed that Design A performed significantly better than Design B on task completion time (p = 0.02) and error rate (p = 0.04), while there were no significant differences between the designs on the other three metrics. What is the main issue with the researcher's approach to analyzing the data?
