Independent and dependent variables are fundamental concepts in research and experimentation, particularly in fields such as science, statistics, and social sciences. Here's how they differ:
### Independent Variable:
- **Definition**: The independent variable is the variable that is manipulated or controlled by the researcher to observe its effect on another variable. It is considered the cause or factor that may influence outcomes.
- **Role**: It is the variable you change in an experiment to see how it affects the dependent variable.
- **Example**: In a study looking at the effect of different amounts of sunlight on plant growth, the amount of sunlight (e.g., hours per day) is the independent variable.
### Dependent Variable:
- **Definition**: The dependent variable is the outcome or response that is measured in an experiment. It is affected by changes in the independent variable and is considered the effect or result.
- **Role**: It is what you measure in the experiment to gauge the impact of the independent variable.
- **Example**: In the same study on plant growth, the height of the plants after a certain period would be the dependent variable, as it depends on the amount of sunlight they received.
### Summary:
In summary, the independent variable is the factor that is changed or controlled in an experiment, while the dependent variable is the outcome that is measured, which responds to changes in the independent variable.
