i did a lab experiement and I do not know what was the control group.
I tested the rates of cellular respiration for:
Germinated, room temperature peas
Non-germinated, room temperature peas
Germinated, cool temperature peas
Which one is the control group and how do you figure it out (by the way, the germinated warm peas had the highest respiration rate while the non-germinated cool temperature had the lowest cellular respiration rate)
It depends on your hypothesis. If your hypothesis was that the germinated would....respiration rate, then your control group was the Non germinated group.
Control groups are always that which are not manipulated.
