9. Experimental Results Experiment One Experiment Two
For file search tasks, people who used SB first did better
In both phases. Along with some other results this suggest
That SB is easier to learn initially than TB.

10. Subjective Results
51 out of 60 people preferred SB overall.

11. Experimental Design Problems
1. Too Many Variables. Attempted to answer too many
questions at once.
2. Most Conclusion are NOT statistically significant.
Even if they were SS – would they apply?
Would the means be different enough to care?
Does this apply to all hierarchies?
c) What about all those failures we through out?
Suggestions
Make users perform only one type of task, but
over many hierarchies, with more samples.
