To summarize, a
strong inductive argument
is one where it is improbable for the conclusion to be false, given that the premises are true. A weak inductive argument is one where the conclusion probably would not follow from the premises, if they were true.
How do you determine whether an inductive argument is strong or weak?
An inductive argument
can always be stronger, always be weaker
. Generally, if there is more than a 50-50 chance that the conclusion will follow from the (presumed) truth of the premises, then it is strong; otherwise it is weak.
How do you know if an argument is strong or weak?
Definition: A
strong argument
is a non-deductive argument that succeeds in providing probable, but not conclusive, logical support for its conclusion. A weak argument is a non-deductive argument that fails to provide probable support for its conclusion.
What qualities makes an inductive argument strong?
An inductive argument is an argument that is intended by
the arguer to be strong enough that, if the premises were to be true, then it would be unlikely that the conclusion is false
. So, an inductive argument’s success or strength is a matter of degree, unlike with deductive arguments.
How do you assess the strength of an inductive argument?
Conclusion: Most students who do well in logic class do well in law. Since the quality of the support for the conclusion of an inductive argument is based upon the quality of the sample, the strength of the argument is based
on how well the sample represents the group referred to in the conclusion
.
What are the 4 types of arguments?
- Type 1: Deductive Arguments.
- Type 2: Inductive Arguments.
- Type 3: Toulmin Argument.
- Type 4: Rogerian Argument.
What are the 2 types of inductive arguments?
- Generalized. This is the simple example given above, with the white swans. …
- Statistical. This form uses statistics based on a large and random sample set, and its quantifiable nature makes the conclusions stronger. …
- Bayesian. …
- Analogical. …
- Predictive. …
- Causal inference.
What is strong and weak evidence?
Strong evidence are facts, clear examples and are related to the topic
. Weak evidence may be a series of opinions or may not be related to the topic.
What are the 5 elements of argument?
- Claim;
- Reason;
- Evidence;
- Warrant;
- Acknowledgement and Response.
What makes strong evidence?
Strong evidence is
accurate, convincing, and relevant to the argument at hand
. It comes from a credible source, and it truly supports the reason it is supposed to prove.
What is inductive argument example?
An example of inductive logic is, “
The coin I pulled from the bag is a penny
. … Therefore, all the coins in the bag are pennies.” Even if all of the premises are true in a statement, inductive reasoning allows for the conclusion to be false. Here’s an example: “Harold is a grandfather.
What is a strong inductive argument?
To summarize, a strong inductive argument is
one where it is improbable for the conclusion to be false, given that the premises are true
. A weak inductive argument is one where the conclusion probably would not follow from the premises, if they were true.
What are the 2 types of logic?
Logos and Logic. Logos: There are two types of logical argument,
inductive and deductive
. In an inductive argument, the reader holds up a specific example, and then claims that what is true for it is also true for a general category.
What are the three key criteria used to evaluate inductive argument?
What do we call a form of inductive reasoning where a student believes that her softball team’s recent winning streak is due to the fact that she has been wearing her good luck jersey? The three general guidelines to keep in mind when testing a plausible hypothesis are:
explanatory power, economy, and predictive power
.
How do you identify an inductive argument?
If there is a general statement in the premises, the argument will always be inductive
. If the conclusion of an argument is a generalization (all) from evidence in the premises (some), the argument will be inductive.
How do you evaluate the strength of an argument?
- Identify the conclusion and the premises.
- Put the argument in standard form.
- Decide if the argument is deductive or non-deductive.
- Determine whether the argument succeeds logically.
- If the argument succeeds logically, assess whether the premises are true.
