Extraneous variables are those that are not the focus of the study but can influence the outcome. While it's often impossible to eliminate their effects entirely, researchers can control for or minimize differential effects of these variables to ensure they do not unduly influence the relationship between the independent and dependent variables. This is done through techniques such as randomization, matching, or statistical control, aiming to isolate the effect of the independent variable on the dependent variable.
