The dependent variable is the number of batteries. The dependent variable is the electromagnet. The independent variable is the number of batteries.
What are some examples of independent and dependent variables?
Independent variable causes an effect on the dependent variable. Example: How long you sleep (independent variable) affects your test score (dependent variable). This makes sense, but: Example: Your test score affects how long you sleep.
How do we know which variable is independent and which variable is dependent?
Independent vs. Dependent Variables | Definition & Examples
- The independent variable is the cause. Its value is independent of other variables in your study.
- The dependent variable is the effect. Its value depends on changes in the independent variable.
