Detailed explanation-1: -Indeed, correlation does not imply causation. Whenever we see a relationship between two variables, it’s wise to be conservative and assume that the relationship is correlational rather than causal. However, this doesn’t mean that correlations are useless.
Detailed explanation-2: -The correlation coefficient should not be used to say anything about cause and effect relationship. By examining the value of ‘r’, we may conclude that two variables are related, but that ‘r’ value does not tell us if one variable was the cause of the change in the other.
Detailed explanation-3: -Causation means one thing causes another-in other words, action A causes outcome B. On the other hand, correlation is simply a relationship where action A relates to action B-but one event doesn’t necessarily cause the other event to happen.
Detailed explanation-4: -Correlational methods don’t have the scope to imply causation. They only give us information about the association between two variables. The correlational design does not omit the likelihood of other extraneous variables affecting the main variables under study.
