Def Of Independent Variable. Independent variables are the variables that the experimenter changes to test their dependent variable. A change in the independent variable amount of light directly causes a change in the dependent variable moth behavior. A dependent variable is the variable being tested and measured in a scientific experiment. Independent variable ĭndĭ-pĕn dənt In mathematics a variable whose value determines the value of other variables.
This is controlled by the experimenting scientist. An independent variable is exactly what it sounds like. Psychol statistics the variable measured by the experimenter. It is a variable that stands alone and isnt changed by the other variables you are trying to measure. The independent variable is what makes the different research groups different from each other. It is called independent because its value does not depend on and is not affected by the state of any other variable in the experiment.

The dependent variable is dependent on the independent variable. In research design independent variables are those that a researcher can manipulate whereas dependent variables are the responses to the effects of independent variables. It is controlled by the value of the independent variable of which it is an index. This might mean changing the amount duration or type of independent variable that the participants in the study receive as a treatment or condition. For example someones age might be an independent variable. For example allocating participants to either drug or placebo conditions independent variable in order to measure any changes in the intensity of their anxiety dependent variable.
