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)

1 answer

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.
