The statement "Both variables must be shown to be independent" is not part of the definition of a cause-and-effect relationship. Instead, a cause-and-effect relationship requires that the independent variable precedes the dependent variable in time, that there is a correlation between the two variables, and that there is no evidence of spurious correlation. The independence or lack of independence of the variables is not a requirement for a cause-and-effect relationship.
