Experiments:

"Careful observations and experimentation with how things behave under different conditions has lead to a revolution in understanding in just about all areas."

"To make observations, and to collect data, one can either passively observe a phenomenon, or one can actively set up certain conditions under which to observe it."

"an experiment is a deliberate manipulation of things in such a way as to efficiently and accurately collect data."

David J. Hand
