There is a strong positive correlation between cigarette smoking and cancer. The tobacco industry makes a big deal out of the fact that no true causal link between smoking and cancer has been established in humans ( all cause and effect studies have been performed on animals). They are right because the research on humans has been correlation in nature.
What is the independent variable?
What is the dependent variable?
I believe the independent variable would be the smoking of cigarettes while cancer is the dependence?
Tell me what you think it is and offer explanation for your reason ? Thank You =]|||you are right.
smoking is the independent variable
cancer is the dependent variable
this is because wherever a cause-effect relationship is being investigated,
the variable representing the cause is the independent variable
