Answer:
A confounding variable is an extraneous factor that is not the main focus of a study but affects the relationship between the independent variable and the dependent variable. It can create a misleading or spurious association between the variables under investigation.One way that a confounding variable can impact an experiment or study is by introducing bias and leading to incorrect conclusions. When a confounding variable is not controlled or accounted for, it can distort the true relationship between the independent and dependent variables, making it difficult to determine the actual cause-effect relationship. This can result in erroneous findings and undermine the validity and reliability of the study's results. To ensure the accuracy of the study, researchers must identify and control for potential confounding variables through proper experimental design, randomization, and statistical analysis.
