What is a confounding variable? provide an example. If the coefficient of determination between two independent variables is 0.20, what is the VIF? If the independent variables explained less than 50% of the variation of the dependent variable, which of the following would be true? a. The coe...
Example: Control variable It is very possible that if a student feels ill, they will get a lower score on the exam. However, we are not interested in measuring health outcomes a part of our research. This makes “health” a good candidate for a control variable. It still impacts our res...

In this type of study design, researchers will quantify two variables of relevance to their research question, and then statistically determine if the two variables are related to one another. For a correlational study, we may ask research questions such as: Is there a relationship between the ...
A third precondition for causation is the lack of a confounding variable (also known as a confounder). You may observe that drinking coffee is correlated with heart disease later in life. Here you have our first two preconditions satisfied: correlation and temporal precedence. However, there may...
