• Answer:-

    A control variable is a factor in an experiment that is kept constant to ensure that the results are due to the independent variable being tested. By controlling these variables, researchers can isolate the effects of the independent variable on the dependent variable, minimizing the influence of other factors. This helps ensure the experiment's validity and reliability. For instance, in a plant growth study, controlling variables like light, water, and soil type ensures that any observed growth differences are due to the variable being tested, such as fertilizer type.
