A variable that can affect both the dependent variable and independent variable, leading to a potential spurious relationship.<\/p>\n<p>A confounder is a variable that is associated with both the independent variable and the dependent variable, and that could therefore be responsible for the observed relationship between the independent variable and the dependent variable. For example, if we were studying the relationship between smoking and lung cancer, a confounder could be age. Older people are more likely to smoke, and they are also more likely to get lung cancer. If we did not control for age, we might conclude that smoking causes lung cancer, when in fact the relationship is due to age.<\/p>\n<p>B is incorrect because a variable that is constant for all data points cannot affect the relationship between the independent variable and the dependent variable. C is incorrect because a variable that is unrelated to the analysis cannot be a confounder. D is incorrect because a variable that is used for visualization only is not a confounder.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;A variable that can affect both the dependent variable and independent variable, leading to a potential spurious relationship&#8221;
