Note:
It is important to remember that the purpose of your investigation is to find the nature of the relationship between the two variables you have chosen. You do not need to find a strong relationship to get a good grade.
However, you must have had a reason behind selecting the two variables in the first place. These variables were not selected randomly from the list given to you.
Either:
You would have selected your variables because you thought they MIGHT have a relationship.
Or
You selected the variables because they are of interest to other parties and the consequences of discovering a relationship could lead to interesting ideas.
To get a good grade, you must justify your selection of variables in your introduction.
