Statistics are essential part of sciences but in a hands of less than mathematically savvy person a lot of harm can be done by applying methods that might or might not apply to the situation. This is a well known problem.  Anyone wanting to work with statistics should really read the following articles. 

Scientific method: Statistical errors
How scientists fool themselves – and how they can stop
Statisticians issue warning over misuse of P values
The problem with unadjusted multiple and sequential statistical testing

This is not to say that statistics are useless but just like with any tool a person working with statistics must understand when the tools can be employed and what the results actually mean.
