What does confounding mean in epidemiology?
distortion
Confounding is one type of systematic error that can occur in epidemiologic studies. … Confounding is the distortion of the association between an exposure and health outcome by an extraneous, third variable called a confounder.

How variables differ from each other?
The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.
