Answer 1

Let’s use this example: you want to see which fertilizer is best at increasing plant height.
Independent variable – this is what you are changing, in this case the fertilizer type.
Dependent variable – this *depends* on the changes you made to the independent variable, or in most cases it’s what you’re documenting and measuring. In this case it is plant height
