Hypothetico-Deductive Method

The hypothetico-deductive model (or method) has been proposed as a description of scientific method. According to this description scientific inquiry and research proceeds by means by formulating hypotheses that can be either proved or disproved through experimentation and observation.

For example, you are testing the theory of gravity. The hypothesis that you are investigating is that whenever a heavy item is dropped it will fall to the ground when dropped. You experiment with several heavy items and find that each time one is dropped it falls to the ground. This hypothesis can be said to corroborate the theory.
