Deductive Argument:

A deductive argument is an argument that makes the claim that its premises supports the conclusion conclusively.

Example;

All men are mortal. (1st premise)

John is a man. (2nd premise)

Therefore John is mortal. (Conclusion)

In the above arguments the premises supports the conclusion conclusively, because there is some logical relationship that is the conclusion necessarily follows from premises. Another important thing is that we often assume or take for granted some premise in deduction to be true, and then draw our conclusion.

Inductive Argument:

On the other hand Inductive argument claims that its premises supports the conclusion with some degree of probability.

Example;

Mr. X is mortal.

Mr. Y is mortal.

…………………….

…………………….

…………………….

Therefore All men are mortal.

In the above argument the premises supports the conclusion with some degree of probability. Though it is highly probable but we cannot say with certainty that, All men are mortal. To be certain we need future evidences too, that is the death of all human beings. In the induction we directly refer to the facts and then make a conclusion.
