The driving conduct per specific across different dashboards could then be compared utilizing a paired t-exam. Driving behaviors could include accelerating time, frequency of braking, and turning velocity. having said that, if the individual only has a single possibility to travel this kind of they can only check a person dashboard, then a t-test could well be ok for data Assessment so long as the individuality in the drivers are well balanced against the two teams (i.e., dashboard A and dashboard B).
