# Statistics: Variables – Independent and Dependent

## Understanding a Variable’s Function

Variables, whether quantitative or qualitative, serve a specific function depending on the type of study being performed and it is important to understand each when designing the study.

### Independent Variable

When designing the study, note those variables which are changing during the scenario, they are considered independent (IV). For example, if determining the effectiveness of a student’s study time related to their grade (outcome), the amount of hours they study from one night to the next would be the independent variable.

### Dependent Variable

Conversely, those variables which are the outcome of the IV variable are the dependent variables(DV).
Using the same example, a student’s changing study hours over time produces a grade (dependent variable) which are the result.

Independent variable represent factors which change and produce dependent variables which are the outcomes. ## One thought on “Statistics: Variables – Independent and Dependent”
