Question

Two events are said to be correlated if

Answer 1

If the change in values of one set doesn't affect the values of the other, then the variables are said to have "no correlation" or "zero correlation." A causal relation between two events exists if the occurrence of the first causes the other.

Answer 2

Causation symbolizes that one effect is the outcome of the experience of the other development; i.e. there is a causal association within the two performances.
