Detailed explanation-1: -In an experiment, an extraneous variable is any variable that you’re not investigating that can potentially affect the outcomes of your research study.
Detailed explanation-2: -What is a confounding variable? A confounding variable, also called a confounder or confounding factor, is a third variable in a study examining a potential cause-and-effect relationship. A confounding variable is related to both the supposed cause and the supposed effect of the study.
Detailed explanation-3: -2. Confounding variables can mask the true cause-and-effect relationship between variables. Suppose we’re studying the ability of exercise to reduce blood pressure. One potential confounding variable is starting weight, which is correlated with exercise and has a direct causal effect on blood pressure.
Detailed explanation-4: -Extraneous Variable When we conduct experiments there are other variables that can affect our results, if we do not control them. Anything that is not the independent variable that has the potential to affect the results is called an extraneous variable.
