An independent variable (IV) is what is manipulated in a scientific experiment to determine its effect on the dependent variable (DV). By varying the level of the independent variable and observing associated changes in the dependent variable, a researcher can conclude whether the independent variable affects the dependent variable or not.
Here are several examples of independent and dependent variables in experiments: In a study to determine whether how long a student sleeps affects test scores, the independent variable is the length of time spent sleeping while the dependent variable is the test score.
An independent variable is the cause while a dependent variable is the effect in a causal research study.
Get the definitions for independent and dependent variables, examples of each type of variable, and an explanation of how to graph them.
Learn about the most popular variables in scientific research, including independent, dependent, control, moderating and mediating variables.
A variable is something that researchers are studying in a research project or experiment. Every scientific experiment involves at least one independent variable and one dependent variable. Discover the difference between these two types of variables and review several examples of each type.
A dependent variable responds to the one or many independent variables and thus, ‘depends’ on those variables. Dependent variables cannot exist without independent variables, and one dependent variable can only be affected by one independent variable during one study.
