If I fertilize tomato plants, they will make more fruit. Independent variable in this exp is:
the application of fertilizer
the number of fruits
the tomato plants
the amount of water they get
2
In the tomato experiment the control would be:
the number of fruits they produced
the amount of fertilizer that a plant got
the amount of light the plants got
the group of tomatoes that didn't get fertilizer
