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, __
The statement 'users of statistics do not need to understand the underlying theory in order to solve real problems' most logically completes the argument.
