I am doing a photography project in Science class and I need to find a control group. I am taking pictures of people and seeing if eye color affects red eye. I said light eyes have a higher chance of getting red eye.|||I would say the control group should consist of all different eye colors looking at the person behind the camera and then directly at the camera lens, both from a certain distance.|||you control is meant to be identical to your experimental in all aspects except for what it it is your testing.
so select people of the same age, life style, race, health as your experimental group.
