Statistics teachers often debate whether to teach the mathematical theories underlying statistics or to focus on the use of statistical methods to solve real problems. This is like the difference between learning to build a car and learning to drive one. Almost all statistics courses teach "building, " and if there is extra time, they may cover a tip or two on "driving. " But, just as ordinary drivers do not need to know how to build a car in order to drive one, __ Which one of the following most logically completes the argument? ['students should not be presumed by their teachers to have a particular goal or purpose in taking a class', 'users of statistics do not need to understand the underlying theory in order to solve real problems', 'statistics should be considered as a discipline that is distinct from mathematics', 'statistics teachers should focus on providing their students with the skills that they are most likely to use']
