Study Notes
- Mathematics Grade 8, Quarter 2, Module 13 focuses on using inductive and deductive reasoning in arguments
- This module aims to help in understanding arguments by defining and differentiating inductive and deductive reasoning, and applying them.
Inductive Reasoning
- Involves gathering specific information, typically through observation and measurement
- Involves use of specific information to formulate conjectures
- Involves generalization or conclusion based on the carefully gathered information.
- Allows making a general rule from specific examples.
- Requires necessary precaution before making a generalization or conclusion.
- A single case that is not true will invalidate the general conclusion
- Analysis and investigation of different cases are important.
Examples of Inductive Reasoning
- The next term in the sequence 10, 20, 30, ... is 40 because these numbers are multiple of 10.
- John, Joan, Josh & Bea are math challengers and are good in mathematics, therefore all math challengers are good in mathematics.
- A chair in the living room is red, the chair in the dining room is red. That means that all the chairs in the house are red.
Deductive Reasoning
- Involves using acceptable facts and proven theorems as proof to draw a specific case or situation
- Allows making a specific conclusion based on a general truth or fact
- Starts from a general statement or fact to conclude into a specific example or claim
Examples of Deductive Reasoning
- Sally does not drink soft drinks, therefore she does not drink Cola.
- Numbers ending in 0 or 5 are divisible by 5. Therefore, 35 must be divisible by 5.
- Right angles measure 90 degrees and since ∠A is a right angle, ∠A measures 90°.
- All mathematics challengers are good in math, therefore Jim, Jane and Jelian are good in mathematics.
