Causation occurs when: two variables tend to move in the same direction. change in one variable does not cause any change in another variable. two variables tend to move in opposite directions. change in one variable is the reason for the change in another variable.
change in one variable is the reason for the change in another variable.
Explanation:
Causation refers to the relationship that exists between cause and effect, in other words how one thing leads to something else happening. Therefore Causation occurs when a change in one variable is the reason for the change in another variable. The first variable being the cause while the second variable is the effect in this scenario.
