Answer:
Hypothetico-deductive model
Explanation:
Hypothetico-deductive model consists of taking some assertions as hypotheses and testing such hypotheses by deducing from them, together with the knowledge that we already have, conclusions that we confront with the facts.This model is applied to obtain predictions from a theory. If the assumptions are true, and the theory is true, deductive reasoning must necessarily reach true conclusions. In case the assumptions are true and the conclusion false, the theory must be false and must be rejected or revised, due to the principle of invalidity.
