The quantitative data analysed statistically and comparative graphs for the web mapping sites
were created indicating the average, minimum and maximum time spent in each task as well
as the average, minimum and maximum number of clicks for obtaining the desirable results.
As the time spent is in strong correlation with the user’s mental effort, the web site where the
user could satisfy the task’s objectives faster was considered as the most usable (Figure 1).
Similarly the web site where the user could satisfy the task’s goal with less steps and
therefore with the lowest number of clicks, was considered as the most usable web site.
