An independent variable is defined as a variable that is changed or controlled in a scientific experiment. The independent variable represents the cause or reason for an outcome. Independent variables are the variables that the experimenter changes to test his or her dependent variable.

In scientific experiments, the independent variable is manipulated while the dependent variable is measured. The independent variable, controlled by the experimenter, influences the dependent variable, which responds to changes.

The independent and dependent variables are key to any scientific experiment, but how do you tell them apart? Here are the definitions of independent and dependent variables, examples of each type, and tips for telling them apart and graphing them.

Independent variable is a variable that is manipulated or changed by the researcher to observe its effect on the dependent variable. It is also known as the predictor variable or explanatory variable. The independent variable is the presumed cause in an experiment or study, while the dependent variable is the presumed effect or outcome.

The independent variable is sometimes called the controlled variable, while the dependent variable may be called the experimental or responding variable. The independent variable is the one you control or manipulate. The dependent variable is the one that responds and that you measure.

The independent variable is the variable that is controlled or changed in a scientific experiment to test its effect on the dependent variable. It doesn’t depend on another variable and isn’t changed by any factors an experimenter is trying to measure.

An independent variable is the variable you manipulate 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.

Quite simply, the independent variable is the state, condition or experimental element that is controlled and manipulated by the experimenter. The dependent variable is what an experimenter is attempting to test, learn about or measure, and will be “dependent” on the independent variable.
