Detailed explanation-1: -An extraneous variable is any variable that you’re not investigating that can potentially affect the dependent variable of your research study. A confounding variable is a type of extraneous variable that not only affects the dependent variable, but is also related to the independent variable.
Detailed explanation-2: -Extraneous variable (EV) is a general term for any variable, other than the IV, that might affect the results (the DV). Where EVs are important enough to cause a change in the DV, they become confounding variables.
Detailed explanation-3: -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.
Detailed explanation-4: -Extraneous variables, also known as confounding variables, are defined as all other variables that could affect the findings of an experiment but are not independent variables.
Detailed explanation-5: -An extraneous variable is eliminated, for example, if background noise that might reduce the audibility of speech is removed. Unknown extraneous variables can be controlled by randomization. Randomization ensures that the expected values of the extraneous variables are identical under different conditions.
