The existence of a relationship

The existence of a relationship

There is a relationship between two variables if the distribution of the dependent variable varies according to the categories of the independent variable

E.g.: in  the above example the distribution of financial status varies according to whether there is a medical condition, so the two are related.

If the data showed the following, there would be no relationship.

MENTAL HEALTH - HAVING A MEDICAL CONDITION

FINANCIAL STATUS

Relatively bad

Relatively good

The existence of the relationship doesn’t depend on which of the variables is the independent one.
