An independent variable is defines as the variable that is changed or controlled in a scientific experiment. ... Independent variables are the variables that the experimenter changes to test their dependent variable. A change in the independent variable directly causes a change in the dependent variable.

One is called the dependent variable and the other the independent variable. The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable. Two examples of common independent variables are gender and educational level.

Independent, Dependent and Confounding Variables. Some variables are manipulated and others are controlled. ... Independent variable (IV) – What the experimenter manipulates to see if it affects behavior. Dependent variable (DV) – The behavior that is measured to see if the IV had an effect.

The independent and dependent variables may be viewed in terms of cause and effect. ... The difference is that the value of the independent variable is controlled by the experimenter, while the value of the dependent variable only changes in response to the independent variable.

Independent variables are those which do not depend on other variables. Dependent variables are those which are changed by the independent variables. The change is caused by the independent variable. In our example salary is the independent variable and the amount you spend is the dependent variable.

Dependent variables A dependent variable represents a quantity whose value depends on how the independent variable is manipulated. y is often the variable used to represent the dependent variable in an equation.

Independent variable: What the scientist changes or what changes on its own. Dependent variable: What is being studied/measured. The independent variable (sometimes known as the manipulated variable) is the variable whose change isn't affected by any other variable in the experiment.

A dependent variable is the variable being tested and measured in a scientific experiment. The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded.

Definitions. 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. ... Here the independent variable is the dose and the dependent variable is the frequency/intensity of symptoms.

The two main variables in an experiment are the independent and dependent variable. 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.

From Wikipedia, the free encyclopedia. In an experiment, the variables used can be classed as either dependent or independent variables. The dependent variable is the possible outcome of the experiment; the effect. It depends on what happens to other variables in the experiment.

Summary: Independent vs Dependent Variable The independent variable is what you change, and the dependent variable is what changes as a result of that. You can also think of the independent variable as the cause and the dependent variable as the effect. ... Constant variables are also important to understand.

The dependent variable is the variable being tested and measured in an experiment, and is 'dependent' on the independent variable. ... In an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable.

The Dependent and Independent Variables The independent variable is the variable that is controlled and manipulated by the experimenter. ... The dependent variable is the variable that is measured by the experimenter. In our previous example, the scores on the test performance measure would be the dependent variable.
