Most studies have extraneous variables of one sort or another. It is significant for the researcher to recognize and control for these variables, either in the study design or through statistical procedures, to preserve the validity of the study results. If a study cannot control for an extraneous variable, the variable has then termed a confounding variable. The manipulation of the independent variable, control of extraneous variables, and randomization is essential to quantitative research.
