Inductive vs. Deductive Reasoning
 DEDUCTIVE REASONING: TAKING GENERAL CASESAND MAKING SPECIFIC EXAMPLESIF Quadrilaterals have 4 sidesTHEN a square is a quadrilateral. Specific InfoDeductivereasoningGeneral InfoDEDUCTIVEREASONINGEXAMPLE: My math teacher is skinnyMy last math teacher was skinnyConclusion by inductive reasoning:All math teachers are skinnyInductive reasoning takes specific examplesand makes sweeping general conclusions. Inductive reasoning is usedto find the next term in a pattern:By inductive reasoning (using the specificexamples to make a general rule to add 10)the next term is...10, 20, 30, 40, 50, DEDUCTIVESPECIFIC CASESGENERALITIESINDUCTIVE  Inductive reasoning(use specific examples to make a general rule) Deductive reasoning(Apply a general rule to specific examples)All even numbers are divisible by 228 is evenTherefore 28 is divisible by 2  Inductive reasoning(use specific examples to make a general rule) Deductive reasoning3,6,9,12,15,The next term is going to be 18(Apply a general rule to specific examples)  Inductive reasoning(use specific examples to make a general rule) Deductive reasoning(My daddy  has curly hairMy brother has curly hairTherefore everyone I am related to has curly hairApply a general rule to specific examples)  Inductive reasoning(use specific examples to make a general rule) Deductive reasoningAn apple a day keeps the doctor away.Joe ate an apple every day.Dr. Dre stayed away.(Apply a general rule to specific examples)  Inductive reasoning(use specific examples to make a general rule) Deductive reasoningJimmy got bitten by a dog .Jimmy is now scared of all dogs.(Apply a general rule to specific examples)  Inductive reasoning(use specific examples to make a general rule) Deductive reasoningThe next term will be 81(1,4,9,16,25,36,49,64Apply a general rule to specific examples)  Inductive reasoning(use specific examples to make a general rule) Deductive reasoning(My soda had a roach in it.All soda has roaches.Apply a general rule to specific examples)  Inductive reasoning(use specific examples to make a general rule) Deductive reasoning(AllSpeederswill beslappedApply a general rule to specific examples)JimmyspedJimmy gotslapped  Inductive reasoning(use specific examples to make a general rule) Deductive reasoningTwo episodes of the Big Bang Theorymade me laugh and laugh LOLOLOLOLTherefore, The Big Bang Theory is always funny.(Apply a general rule to specific examples) Jimmy's next will be named Apricot-Mist Mu Mu Mu MuJimmy named his kids Apricot-Mist,Aprocot-Mist Mu,Apricot-Mist Mu Mu, andApricot-Mist Mu Mu Mu Inductive reasoning(use specific examples to make a general rule) Deductive reasoning(Apply a general rule to specific examples) DEDUCTIVEThe EndSPECIFIC CASESGENERALITIESINDUCTIVE
