Chart
3.1:
Graph showing average time to correct completion for each task, grouped by which version
of the site. In general Static-Shallow had the
fastest average times, except for task 5. Below
is the chart of data.

Table
3.2:
Indicates if the results are statistically significantly
different (p < 0.05) for tasks compared with Static-Deep.
These
results show that Dynamic-Deep was never faster than Static-Shallow and was
slower for only task 5.
Static-Shallow was faster than Static-Deep for tasks
1, 4, 6, 7, 11, and 12, but slower for Task 8.
We
used the one way ANOVA to test each task if the results were statistically significant
based on the critical values. Dynamic-Deep and Static-Deep were compared for the menu interface. Static-Deep and Static-Shallow were compared for link
hierarchy.
Since
there is only one task (5) that Dynamic-Deep and Static-Deep had that indicated a statistical
significance, we assume that Static-Deep has no performance advantage over Dynamic-Deep in
finding a link. On the other hand, Static-Shallow
and Static-Deep had results for a little over half the tasks that indicate some statistical
significance, so we assume that Static-Shallow has some performance advantage over Static-Deep. And since Static-Deep has comparable times with
Dynamic-Deep, then we also assume that Static-Shallow has some performance advantage over Dynamic-Deep.

Table
3.3 :
Shows the number of people who could recall correctly the exact name of the main category.
Only
one subject had correctly recalled all four of the main categories. Many subjects, however, could recall the idea of
the category or some permutation of the name. For
example, 19 subjects recalled business(es) or business info as a category and for citizen
services 13 subjects put community or a phrase with community in it. Some other categories that subjects came up with
include: lifestyles, life guide, recreation, life in MD, Maryland citizens, around and
about town, services for citizens, travel, transportation, education, Maryland resources,
family, individual, Maryland places to see, citizen/community and life. In comparing the total number of correct
categories recalled, Static-Shallow had 9 total, Dynamic-Deep had 5 and Static-Deep had 3. The
recall error rate is the number of incorrect categories the subjects named when asked to
name the 4 main categories.

Table
3.4:
Shows the recall error rate when asking the subject to name the 4 main categories after
completing the first task set. Subjects that
used Static-Shallow to complete tasks 1 to 3 seem to have a little better recall rate than
Dynamic-Deep and Static-Deep.

Chart
3.2:
User Preference - shows that most users prefer Static-Deep, then Static-Shallow.
Chart
3.3:
Ease of use - shows that most users found the static, shallow version easier to use.
Chart
3.4 :
Most Visually Appealing even though 50% of the users find that Dynamic-Deep is the
most visually appealing it ranks behind Static-Shallow on user preference and Static-Shallow ranks
last in being considered visually appealing.
