Explanation:

To establish a correlation one must first understand that the correlation is a relative term in that it can only be established between two entities that are essentially changing in reference to something,

Only in their change can a pattern be established that can then be worked upon as a correlation.

Thus a relationship between certain variables must exist for something to be a correlation and not simply a connection drawn,
