Detailed explanation-1: -The variable that the scientist changes during their experiment are the independent variable.
Detailed explanation-2: -The independent variable is the one that is changed by the scientist. To insure a fair test, a good experiment has only ONE independent variable. As the scientist changes the independent variable, he or she records the data that they collect.
Detailed explanation-3: -In an experiment, the independent variable is the variable that is varied or manipulated by the researcher. The dependent variable is the response that is measured. One way to think about it is that the dependent variable depends on the change in the independent variable.
Detailed explanation-4: -An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment. The dependent variable is ‘dependent’ on the independent variable.
