• Answer:-

    Controlled variables are constants in experiments, ensuring that the outcome is due to the independent variable alone. For instance, in a plant growth study, controlled variables might include the amount of sunlight, type of soil, and water provided. In drug trials, factors like age, diet, and activity level of participants are controlled to ensure that any observed effects are due to the drug itself. By keeping these variables constant, researchers can confidently attribute changes in the dependent variable to the independent variable, making their findings more reliable and accurate.
