TFY ch 11

Inductive reasoning is a method used to discover new information or to supply missing information. When we use inductive reasoning, we observe, test, and check things out in some systematic fashion. The inductive method is also called the empirical or scientific method.Induction can be done through sensory observation, enumeration, analogous reasoning, causal reasoning, and from pattern recognition.Inductive reasoning is used as a method for obtaining information when it would be impossible to examine all the data available. This is done by taking statistical samplings or by making extrapolations.Hasty generalization is the fallacy of basing a conclusion on insufficient evidence.The either-or fallacy, or false dilemma, is an argument that oversimplifies a situation, asserting that there are only two choices, when actually other alternatives exist.Inconsistency in evidence is the fallacy of offering evidence that contradicts the conclusion.The slippery slope is the fallacy of claiming without sufficient proof that permitting one event to occur would lead to a chain reaction that could not be stopped. It ignores the many variables or unknowns in the situation
TfY Chapter 11 Exercise p.303- Inductive Reasoning and Inductive Fallacies: How Do I Reason from Evidence?

1. Induction: Is an argument the truth of whose premises would not serve to guarantee the truth of its conclusion, yet would provide some evidence for it. Sometimes said to be "inductively but not deductively valid".
2. Reasoning: Is the act of using reason to derive a conclusion from certain premises. There are two main methods to reach a conclusion. One is deductive reasoning, in which given true premises, the conclusion must follow (the conclusion cannot be false). This sort of reasoning is non-ampliative - it does not increase one's knowledge base, since the conclusion is self-contained in the premises. A classical example of deductive reasoning are syllogism.

3. Empirical: Refers to that which is based on observation or experience rather than on theory.
4. Scientific methods: Is a body of techniques for investigating phenomena and acquiring new knowledge, as well as for correcting and integrating previous knowledge. It is based on gathering observable, empirical and measurable evidence subject to specific principles of reasoning, the collection of data through observation and experimentation, and the formulation and testing of hypotheses.

5.Inductive reasoning: A type of type of mathematical reasoning which involves observing patterns and using those observations to make generalizations.
