Research Topics Independent And Dependent Variables PDF
What Are Independent and Dependent Variables?
Check out independent and dependent variables:-
Independent Variables
Definition: These are the factors you change or control in an experiment.
Characteristics
- Controlled by You: You decide how these variables change.
- Purpose: To see if they affect other variables.
Examples
- Temperature: Changing the temperature to see how it affects plant growth.
- Teaching Methods: Using different methods to see which one improves student test scores.
Dependent Variables
Definition: These are the factors you measure or observe to see the effect of the independent variables.
Characteristics
- Measured by You: You observe or record these to see the impact of the changes you made.
- Purpose: To see the outcome of changes in independent variables.
Examples
- Plant Growth: Measuring how much the plants grow with different temperatures.
- Test Scores: Checking student test scores to see which teaching method works best.
This should help make the concepts clearer and easier to understand!
