RESEARCH METHODOLOGY

Detailed explanation-1: -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-2: -The independent variable (sometimes known as the manipulated variable) is the variable whose change isn’t affected by any other variable in the experiment. Either the scientist has to change the independent variable herself or it changes on its own; nothing else in the experiment affects or changes it.

Detailed explanation-3: -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.

Detailed explanation-4: -Independent Variable: The variable that is changed or tested by the scientist; the thing that is different between experimental groups. Single factor in an experiment that the experimenter changes.
