Good morning from Cleveland, Ohio!

Let's see if we can, together, shed a little light on your question. Just follow along with me and you will likely come to the answer before I finish answering your question.

First of all, don't let research and statistics scare you. For the most part statistical processes are nothing more then that which we all learned in public school; namely, arithmetic, subtraction, multiplication and division. Alone the numbers hold no power and it is not until one sets up a research investigation that statistics become important.

The first step in any research investigation is to develop a "gut" feeling that something is not right or a situation has not been completely and satisfactorily investigated, or that a new idea needs some support for acceptance. Now... stay with me OK? :-) We all know that "gut" feelings are just that -- feelings. To make sense out of our research feelings we must put these feelings into "question" form. See... simple enough. And, a research question is just that: A gut feeling put into question form. For example... say you have a gut feeling that partying too much during your freshman year will have a tendency to lower your ...
