By using random assignment, researchers are able to control for confounding variables, which are other factors besides the independent variable that may influence research results.
What factors in research are confounding variables?
- A factor other than the one being researched that is linked to both the condition being studied (the dependent variable) and the factor being studied is known as a confounding variable (confounder) (independent variable).
- The effects of one variable on the disease under study may be distorted or concealed by the impacts of a confounding variable. You must take the effect of confounding variables into account to ensure the internal validity of your study.
- If you don't take them into consideration, you can overestimate or underestimate the causal relationship between your independent and dependent variables, or you might even discover a causal association when there isn't one.
