Preparation for Test #2, Jan. 27

We will be having our second test on Tuesday, Jan 27. It will cover most of Chapter 3.
You do not have to know the common patterns of INDUCTIVE REASONING, pp.70-74; or inductive cogency and strngth, pp. 80-83.
HOWEVER be sure you:

1) do exercises in the book. I strongly suggest Exercises 3. 2, 3.3, and 3.5.

2) do the website T/F quiz and the multiple choice quiz.

3) make sure you know the stuff relating to deduction on the website chapter outline.

4) While we are emphazising deductive arguments, be sure you are able to distinguish deductive from an inductive arguments, and understand the concepts of validity and soundness. Be able to list and identify the 5 common patterns of deductive reasoning.
5) review the handouts.

Be familiar with these concepts and able to identify and use them:

  • deduction

  • induction

  • strict necessity

  • logical impossibility

  • physical impossibility

  • affirming the antecendent (modus ponens)

  • denying the consequent (modus tolens)

  • conditional (hypothetical) statement;

  • syllogism

  • hypothetical syllogism

  • categorical syllogism

  • argument by elimination

  • argument based on mathematics

  • argument from definition

  • valid argument

  • invalid argument

  • sound argument

  • unsound argument

  • chain argument

  • Be able to

    1) identify the key differences between deductive and inductive arguments (cf. p.58)

    2) tell whether an argument is deductive or inductive, by means of indicator word test, strict necessity test, and the common pattern test.

    3) list the common deductive indicator words;

    4) list the common inductive indicator words

    5) Identify the five common patterns of deductive reasoning

    6) identify arguments that are valid and that are invalid

    7) identify arguments that are sound and that are unsound

    For this test, YOU DON'T NEED TO MEMORIZE THE SIX COMMON PATTERNS OF INDUCTIVE REASONING...we'll do that in our next unit. You DO need to know how to tell the difference between a deductive and an inductive argument; but at this point, you can figure that anything I give you that doesn't fit one of the deductive forms will be inductive.

    The test will have the following sections:

    1. Ten T/F questions, worth 2 points each (total 20 points)

    2. Twenty multiple choice questions, worth 2 points each (total 40 points)

    3. Ten "Identify Arguments as valid or invalid" questions, worth 2 points each (total 20 points)

    4. Ten "Determine whether the argument is Sound or Unsound" questions, worth 2 points each, (total 20 points)
