Understanding Deduction and Induction

The video tutorial explains the differences between deduction and induction. Deduction involves starting with a general statement and reaching a specific conclusion, while induction begins with specific observations to form a general conclusion. Examples are provided using family members to illustrate both methods. Deduction offers certainty if premises are true, whereas induction provides a probable conclusion that becomes more likely with more premises. The video also discusses how exceptions can affect conclusions in both methods.

What is the primary difference between deduction and induction?

• Deduction starts with specific premises and ends with a general conclusion.

• Induction starts with general premises and ends with a specific conclusion.

• Deduction starts with general premises and ends with a specific conclusion.

• Induction starts with specific premises and ends with a specific conclusion.

In the deduction example, what specific conclusion is drawn about John?

• John does not use money.

• John is not a member of the family.

• John uses money.

• John is a distant cousin.

Which of the following is a premise used in the induction example?

• All family members use money.

• John is a family member.

• My mother uses money.

• Joe is abducted by aliens.

What general conclusion is drawn from the induction example?

• Only parents use money.

• All relatives use money.

• Some family members do not use money.

• All family members use money.

How does the certainty of conclusions differ between deduction and induction?

• Deduction conclusions are always probable.

• Induction conclusions are always certain.

• Induction conclusions are certain if premises are true.

• Deduction conclusions are certain if premises are true.

What happens to the deduction conclusion if a premise is proven false?

• The conclusion remains true.

• The conclusion is unaffected.

• The conclusion becomes false.

• The conclusion becomes more probable.

In the induction example, what is the impact of more premises being true?

• The conclusion becomes more probable.

• The conclusion becomes less probable.

• The conclusion becomes certain.

• The conclusion becomes false.
