Can You Identify Experimental and Control Group In The Experiment?

John Obtains Two Healthy Plants Of The Same Variety And Size.He Plants Each Plant In The Same Type of Pot%26amp;The Same Brand Of Potting mix.He Then Places Both Plants In The Same Window of The House.He Waters PlantA every Other day with 250ML of Water %26amp;Waters Plant B once A Week With 250ML water.He Measures The Height Of The Plants Once a Week For 6Weeks





Identify The Experimental and Control Group In The Experiment|||The control group is the one you are comparing your experimental group with. In this case, it is not clear which is which. If say I wanted to know the optimal amount of watering for a plant, I could set watering once a week as the control group. I would then have plants for watering 6 days, 5 days, 4, days, etc. a week. These groups would be the experimental ones in which I compare with my plant that was watered once a week.
