Figure 19 shows the average number of
notification messages versus the number of browse requests, and the average
number of browse requests versus the number of notification messages. There is
little correlation between the two variables: the number of notification
messages fluctuates widely with the number of browse requests; similarly, the
number of browse requests also shows no obvious trend with respect to the
number of notification messages. The correlation coefficient between these two
variables is 0.265 when considering all users, and 0.125 when considering only
wireless users. The low correlation coefficients implies that web site designers
cannot predict a user's browsing activity based on his/her notification
activity, and vice versa.
