Independent variable: FERTILIZER.
This is the variable that you think affect your dependent variable and so you change it and use different types of it to confirm your prediction.
Dependent variable: COLOR.
That is the variable you are interested in.

Experimental groups: THE GROUPS THAT RECEIVED FERTILIZERS.
The experimental group is the group that receives treatment.
