Great question.  What do 240 positives out of 1350 observations
indicate?  For starters it indicates the process identifies safe
behaviors and doesn't just focus on at-risk behaviors. It also indicates
a decent number of observations, which helps reduce uncertainty in your
stats. Beyond that it really depends on what behavior you are observing.
For example, here in Montreal if the observation was 240 drivers out of
1350 coming to a full stop at a stop sign, it would simply mean that 240
drivers are from Vermont ;-)
