Flashcards

Inductive Reasoning

A type of reasoning that starts with specific examples and draws a general conclusion. It's like noticing a pattern and making a guess about what will happen next.

Deductive Reasoning

A type of reasoning that starts with general statements (often considered facts) and uses logic to reach specific conclusions. It's like applying a rule to a situation.

Generalization

A conclusion reached through inductive reasoning. It's a broad statement based on specific examples, but it might not always be true.

Accepted Facts

A statement that is commonly accepted as true. These form the starting point for deductive reasoning.

Study Notes

Mathematical Competency (Numeracy)

  • Numeracy is the ability to think and communicate using numbers, similar to literacy's function in the world of words.
  • Numeracy and literacy often overlap
  • Examples of numeracy skills include calculating, estimating, identifying patterns, testing assumptions, investment decisions, outcome prediction, and code deciphering.
  • Mathematical skills are crucial for problem-solving in various fields, like the construction industry (as demonstrated by Ned Pelger) and consumer decisions (as shown by Super Crunchers).
  • Everyday life is becoming increasingly quantitative, demanding broader mathematical familiarity.

Inductive Reasoning vs. Deductive Reasoning

  • Inductive Reasoning: Starts with specific observations and leads to a general conclusion.
    • Example: Every time you walk outside, you sneeze; therefore, you carry tissues when going outside.
    • This type of reasoning is a generalization.
  • Deductive Reasoning: Starts with generally accepted facts and uses logic to reach a specific conclusion.
    • Example: Believing that experiencing perfume on others is a good way to sell it; therefore, offering free samples.
    • Deductive reasoning produces stronger arguments than inductive reasoning if the initial statements are true, leading to definitive conclusions.
