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: -An independent variable is the variable you manipulate, control, or vary in an experimental study to explore its effects. It’s called “independent” because it’s not influenced by any other variables in the study.
Detailed explanation-3: -So the independent variable is the factor being tested and the dependent variable is the factor being observed and measured. In a controlled experiment all variables are kept the same except the one that is being tested.
