Dr Vance wanted to investigate whether there is a difference in the number of navigation errors made during a flight simulation task between professional commercial drone pilots and recreational hobbyist pilots. She recorded the number of flight errors (on a scale of 0 to 50) for a sample of 10 professional pilots and 10 hobbyist pilots.
