Question

If we find that there is a linear correlation between the concentration of carbon dioxide in our atmosphere and the global temperature, does that indicate that changes in the concentration of carbon dioxide cause changes in the global temperature? Choose the correct answer below. A. No. The presence of a linear correlation between two variables does not imply that one of the variables is the cause of the other variable. B. Yes. The presence of a linear correlation between two variables implies that one of the variables is the cause of the other variable.

Explanation / Answer

The correct answer is (B)

Because if there is linear relationship exist between then one variable change then the other also changes in approximate some constant (regression coefficient).

Also if there is positive correlation between the two variables then one is increase cause the other also increase and one is decrease cause the other also decrease that is the direction of the two variables are same.

And if there is negative correlation between the two variables then one is increase cause the other is decrease and one is decrease cause the other also increase that is the direction of the two variables are opposite.
