These ways include: The third variable problem or a confounding factor exists when a third variable that is not being measured causes the changes in the variables. Since the experimental research has better provisions of proving results, then it exhibits various advantages. Different life experiences can cause people to react to the same situation in different ways. Web721 Smith Rd. A High Level Of Control The experimental method gives researchers a high level of control since they choose the IVs and DVs, how to measure them, and the procedure of the study. These outcomes include a positive correlation, negative correlation, and no correlation. This is the idea that the order of conditions tested may influence the study's results. Results may not be able to be reproduced, meaning the results have low reliability. Is it acceptable for research following the scientific method to be based on the researchers' subjective opinion?
