Study Notes
Dependent Variable
A dependent variable is a variable being measured or observed in an experiment, often in response to changes made to an independent variable.
Key Characteristics:
- Its value changes in response to changes in the independent variable
- Its value is being measured or observed
- It is the outcome or result being studied
Example:
- In an experiment to see how much water a plant needs to grow, the amount of water given to the plant is the independent variable, and the growth of the plant is the dependent variable.
Types of Dependent Variables:
- Quantitative Dependent Variable: A dependent variable that can be measured numerically, such as height, weight, or temperature.
- Qualitative Dependent Variable: A dependent variable that cannot be measured numerically, such as color, texture, or flavor.
Importance:
- Helps to identify the effect of the independent variable on the outcome
- Allows researchers to draw conclusions about the relationship between the independent and dependent variables
