When doing experimental research, why is it important to control for everything except the independent variable?

Question

Quizplus · Accepted Answer

Controlling for everything except the independent variable ensures that any changes in the dependent variable can be attributed solely to the independent variable. This allows researchers to draw clear conclusions about what influences the dependent variable without the interference of other variables. Controlling for multiple variables also minimizes the risk of confounding variables, or variables that could affect the dependent variable, which could lead to unreliable or inaccurate results. It is important for the integrity and validity of the experimental research process.
