How come you are explaining everything for my math course and suddenly I find this helpful video for my research course? Do you just know everything?

What happened to the black background?

[RachelPun]

Experiments would allow playing around with different variables but still, wouldn't an experiment like in this example be simply a correlation like that in the observational study example? The parameters measured are still just computer time and blood pressure. I think to differentiate the two would maybe need measurement of movement and activities on computer (ambient music VS tasks etc.) as well.
