Here's a breakdown:
* Independent Variable: This is the factor that is being manipulated or changed by the experimenter.
* Dependent Variable: This is the factor that is being measured or observed in response to changes in the independent variable. It's the outcome you're trying to understand.
Think of it this way:
* Independent Variable: The cause.
* Dependent Variable: The effect.
Examples:
* Experiment: Studying the effect of different fertilizers on plant growth.
* Independent variable: Type of fertilizer.
* Dependent variable: Plant height.
* Experiment: Investigating how temperature affects the rate of chemical reaction.
* Independent variable: Temperature.
* Dependent variable: Reaction rate.
Key Points:
* The dependent variable is dependent on the independent variable. Its value changes in response to changes in the independent variable.
* It's important to carefully define and measure the dependent variable to ensure accurate results.
Understanding the dependent variable is crucial for interpreting experimental results and drawing meaningful conclusions.
