Website Structural Navigation

Results

This chart shows that for all three tasks, the time to complete the problem was less for those with navigation bars. Based on this data, it can be assumed that the users with navigation bars used them in some way to their advantage.

Test 1

Test 2

Test 3

Web Experience

These three graphs show the web expertise vs. time on each task. Test #1 falls within the expected results (without navigation bars take longer). However, test #2 and #3 show major differences. For test #2, the times are very similar—the one novice user throws off the data. Test #3 shows the expected results for Advanced and Power Users, but unexpected results for Intermediate users.
