Inductive and Deductive Reasoning

Arguments Premise: statement upon which an argument is based or from which a conclusion is drawn Premise is either true or false Arguments: Consist of one or more premises and one conclusion or claim, which is drawn from those premises

Deductive Reasoning: In deductive, the conclusion is based on one or more premises that state a generalization. It usually states a generalization or fact and ends with a conclusion about something specific. General Premise: All dogs are mammals. Conclusion: My dog Rover is a mammal. All women like chocolate. Ms. Rathmann is a woman. Therefore, Ms. Rathmann likes chocolate. to Specific

Inductive Reasoning: Works the other way around Inductive Reasoning: Works the other way around. Moves from premises that state specific facts and observations to a broader generalization or conclusion drawn from those premises. Premise: My dog has fur. Premise: My friends’ dogs have fur. Conclusion: Therefore, all dogs have fur. My mom likes chocolate. My sister likes chocolate. Therefore, all women like chocolate. Specific to General In inductive arguments, the premises make it likely the conclusion is true, but it is possible for the conclusion to be false even if the premises are true.
