I am testing on the effects that light has on students, I am testing florescent light (Inside a home) and sunlight (outside in the park). My question is on what would the control group would be?|||The students with the beer.|||You are testing to see if there is a difference between the group who does a concentration task in artificial light (florescent light) and the group that does a concentration task in natural light (sunlight).
The group who do the task in sunlight will be able to concentrate better than the other group.
The group who do the task in artificial light must have the curtains closed, to block out the sunlight.
Psychologists try to copy the blue light from the sky to make people more alert, so sunlight is the best light:
