Question

Quizplus · Accepted Answer

Confounding variables are variables that can affect the outcome of an experiment but are not being studied. Therefore, researchers want to avoid their presence in order to ensure that the results are as accurate and reliable as possible. Dependent and independent variables are necessary components of an experiment and cannot be avoided. Random assignment, while important, does not directly relate to the presence of confounding variables.
