Furthermore, double-threaded studies can help to reduce the impact of confounding variables on the research findings. Confounding variables are those factors that influence the outcome of a study but are not directly related to the research question being investigated. By controlling for these variables in both studies, researchers can ensure that any observed differences between the two groups are due to the experimental manipulation rather than other extraneous factors.
