Deductive and Inductive Arguments Argument = def A group of statements, one or more of which are claimed to provide support for, or reasons to believe, one of the other statements. Deductive argument = def An argument in which the arguer claims that it is impossible for the conclusion to be false given that the premises are true. Inductive argument = def An argument in which the arguer claims that it is improbable that the conclusion be false given that the premises are true.
Deductive and Inductive Arguments Example, deductive argument: All movie stars have spent some time in rehab. Harrison Ford is a movie star. Thus, Harrison Ford has spent some time in rehab. Example, inductive argument: A large number of movie stars have spent some time in rehab. Harrison Ford is a famous movie star. Hence, we can justifiably infer that Harrison Ford has spent some time in rehab.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
