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.

Subjective Results
51 out of 60 people preferred SB overall.

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.
