The factor that the experimenter purposefully manipulates or changes during an experiment is the Independent variable.
The Independent variable in an experiment is the element that the experimenter consciously modifies or adjusts. In a scientific experiment, an independent variable is a variable that is altered or under control. It symbolizes the root cause or motivation behind a result.
The variables that the investigator modifies to test their dependent variable are known as independent variables. The dependent variable changes as a direct result of changes in the independent variable. It is assessed and recorded how the influence affects the dependent variable. The element that you deliberately alter or control to observe its impact is known as the independent variable.
