Detailed explanation-1: -A general limitation of a correlational study is that it can determine association between exposure and outcomes but cannot predict causation.
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: -The third variable and directionality problems are two main reasons why correlation isn’t causation. The third variable problem means that a confounding variable affects both variables to make them seem causally related when they are not.
Detailed explanation-4: -Correlation Does Not Indicate Causation Correlational research is useful because it allows us to discover the strength and direction of relationships that exist between two variables. However, correlation is limited because establishing the existence of a relationship tells us little about cause and effect.
