The Role of Dependent Variables in Scientific Research
Understanding Dependent Variables
In scientific research, a dependent variable is the variable being measured or observed that is affected by the manipulation of another variable, known as the independent variable. It is the outcome of the experiment that the researcher is interested in studying and understanding.
Examples of Dependent Variables
For example, in an experiment examining the effects of fertilizer on plant growth, the height of the plants would be the dependent variable. The researcher would measure the height of the plants after varying the amount of fertilizer applied, and the differences in height would be attributed to the manipulation of the independent variable (fertilizer).
