In restriction, you restrict your sample by only including certain subjects that have the same values of potential confounding variables. How do you control for confounding
How Does Confounding Variable Affect The Validity Of The Study? Confounding variables are common in research and can affect the outcome of your study. This is because the external influence from the confounding variable or third factor can ruin your research outcome and produce useless results by suggesting a non-existent connection between variables.
