what is the difference between a deductive and an inductive argument?
256433
Deductive arguments have unassailable conclusions assuming all the premises are true, but inductive arguments simply have some measure of probability that the argument is true—based on the strength of the argument and the evidence to support it.

The main difference between inductive and deductive reasoning is that inductive reasoning aims at developing a theory while deductive reasoning aims at testing an existing theory.

A deductive argument is said to be valid if and only if it takes a form that makes it impossible for the premises to be true and the conclusion nevertheless to be false. ... A deductive argument is sound if and only if it is both valid, and all of its premises are actually true. Otherwise, a deductive argument is unsound.

Inductive and deductive reasoning both strive to construct a valid argument. ... Therefore, inductive reasoning moves from specific instances into a generalized conclusion, while deductive reasoning moves from generalized principles that are known to be true to a true and specific conclusion.

A deductive approach involves the learners being given a general rule, which is then applied to specific language examples and honed through practice exercises. An inductive approach involves the learners detecting, or noticing, patterns and working out a 'rule' for themselves before they practise the language.

An argument is a rationale in which the reason functions as evidence in support of the conclusion. Its purpose is to provide a rational basis for believing the conclusion to be true. An explanation is a rationale in which the conclusion represents an accepted fact and the reason represents a cause of that fact.

Deductive reasoning applies general rules to make conclusions about specific cases. Inductive reasoning observes patterns in specific cases to infer conclusions about general rules.

a deduction is conclusion, whereas a hypothesis is a preliminary explanation.

The main difference between inductive and deductive approaches to research is that whilst a deductive approach is aimed and testing theory, an inductive approach is concerned with the generation of new theory emerging from the data. ... The aim is to generate a new theory based on the data.

Lesson Summary We've learned that inductive reasoning is reasoning based on a set of observations, while deductive reasoning is reasoning based on facts. Both are fundamental ways of reasoning in the world of mathematics.

Terms in this set (4) Inductive reasoning is the process of reasoning that a rule or statement is true because specific cases are true. ... Deductive reasoning is the process of using logic to draw conclusions from given facts, definitions and properties.

Inductive Reasoning. During the scientific process, deductive reasoning is used to reach a logical true conclusion. Another type of reasoning, inductive, is also used. ... It is important to learn the meaning of each type of reasoning so that proper logic can be identified.

Validity and soundness are properties of deductive arguments. Since the premises of an inductive argument do not necessitate the truth of its conclusion, inductive arguments cannot be valid. ... A cogent argument is one that the truth of its premise makes the conclusion more likely to be true than false.

Inductive reasoning does not guarantee a true result, but it does provide a means of making a conjecture. With deductive reasoning, we use general statements and apply them to spe- cific situations.

They are deductive when they are used to test hypotheses derived from an existing theory and inductive when data is collected in order to develop a theory. ... Interviews and focus groups can also be used inductively or deductively , though they are more commonly used inductively.

Key points. Deduction moves from idea to observation, while induction moves from observation to idea. Deduction moves from more general to more specific, while induction moves from more specific to more general.
