Explanation:

In correctional design, the main focus of the researcher is to find out the relationships that will be naturally formed if two or more variables are paired with one another.

But, sometimes the relationships that are naturally formed do not necessarily caused by the interaction by the variables.

Here is an example:

Variable 1 : Older age

Variable 2: Conservatism

On average, as people grow older , people tend to have a more conservative political view compared to the younger generations. (There is a correlation between the two)

But, the conservative ideology is not necessarily caused by the age itself. Inability to follow the current cultural trend would more likely play a bigger factor.
