Detailed explanation-1: -Confounding variables affect both the independent and dependent variables. They influence the dependent variable directly and either correlate with or causally affect the independent variable. An extraneous variable is any variable that you are not investigating that can influence the dependent variable.
Detailed explanation-2: -A confounding variable is a type of extraneous variable that is associated with both the independent and dependent variables. An extraneous variable is anything that could influence the dependent variable.
Detailed explanation-3: -Confounding variables are those that affect other variables in a way that produces spurious or distorted associations between two variables. They confound the “true” relationship between two variables.
Detailed explanation-4: -In research studies, confounding variables influence both the cause and effect that the researchers are assessing. Consequently, if the analysts do not include these confounders in their statistical model, it can exaggerate or mask the real relationship between two other variables.
