Deductive reasoning draws conclusions that are necessarily true from accepted statements, while inductive reasoning draws conclusions that are probable but not certain based on past observations. Deductive reasoning ensures conclusions are true if hypotheses are true, whereas inductive reasoning concludes something is likely true given several past examples but may not be true in all cases.
