An <B>independent variable</B> is the potential stimulus or cause, usually directly manipulated by the experimenter, so it could also be called a manipulative variable.
A <B>dependent variable</B> is the response or measure of results.
The <B>hypothesis</B> is the statement about how you think the experiment will turn out. For example:
Ho: Coffee has no effect.
Ha: Coffee makes people more alert.
A <B>correlation coefficient</B> is a number, varying between -1 and +1, indicating the degree of relationship between two variables.
I hope this will help you make decisions on this question and others.
