The following statements describe a concept: it was suggested by Karl Popper as a description of scientific method; scientific inquiry proceeds by formulating a hypothesis that could conceivably be falsified by a test on observable data; a test that runs contrary to the prediction falsifies the hypothesis, otherwise it is corroborated. Which concept is being referred to?
AHypothetico-deductive method ✓ Correct
BHypothetico-inductive method
CInductive method
DDescriptive method
Correct answer: (A) Hypothetico-deductive method — The concept described, based on falsifiable hypotheses, is the hypothetico-deductive method, so that is the answer.
Explanation
★The concept described, based on falsifiable hypotheses, is the hypothetico-deductive method, so that is the answer.
★Karl Popper offered this as a description of how scientific method works.
★The researcher frames a hypothesis that could be shown false by a test on observable data.
★If a test contradicts the prediction, the hypothesis is falsified; if not, it is corroborated.
★This deducing of testable predictions from a hypothesis is the hypothetico-deductive method.
★Purely inductive and descriptive methods do not centre on falsifiable prediction, so this is the hypothetico-deductive method.
