Quizplus · Accepted Answer

Controlling extraneous variables is important in scientific research to ensure that the results are accurate and reliable. Extraneous variables are any variables other than the independent variable that may influence the dependent variable, and if they are not controlled, they can lead to erroneous conclusions. Therefore, it is crucial to control extraneous variables as much as possible to increase the internal validity of the study.
