Document Summary
11. 3 seven reasons why two variables might be revealed. 1) explanatory variable is the direct cause of the response variable. 2) response variable is causing a change in the explanatory variable (reverse, or reciprocal causation: e. g. downward spiral or gentrification of an urban neighborhood. 3) explanatory variable is contributing, but not the sole cause: e. g. carcinogen in diet is not sole cause of cancer, but rather a necessary contributor to it. 4) confounding variables may exist: a confounding variable is related to the explanatory variable and affects the response variable. So can"t determine how much change is due to the explanatory and how much is due to the confounding variable(s) E. g. happiness confounded with emotional support in explaining longevity. 5) both variables must result from a common cause: e. g. verbal sat and gpa: causes responsible for one variable being high (or low) are same as those responsible for the other being high (or low)
