What is the role of logic in scientific reasoning?

• Logic is essential for formulating hypotheses, drawing conclusions, and evaluating evidence in scientific reasoning.

• Logic is only used for mathematical proofs.

• Logic is irrelevant to the development of theories.

• Logic has no impact on scientific experiments.

Define an If-Then statement and provide an example.

• If I finish my homework, then I will go to bed.

• If it is raining, then I will take an umbrella.

• If it is sunny, then I will wear a coat.

• If the alarm goes off, then I will ignore it.

How does conditional probability differ from regular probability?

• Conditional probability is always higher than regular probability.

• Regular probability does not depend on any events.

• Conditional probability differs from regular probability by considering the occurrence of a related event.

• Conditional probability is only used in statistics.

What are the main rules of inference used in logical reasoning?

• Modus Ponens, Modus Tollens, Disjunctive Syllogism, Hypothetical Syllogism, Universal Instantiation

• Affirming the Consequent

• Denying the Antecedent

• Constructive Dilemma

Explain the difference between deductive and inductive reasoning.

• Deductive reasoning is top-down logic, while inductive reasoning is bottom-up logic.

• Inductive reasoning is always more reliable than deductive reasoning.

• Deductive reasoning involves making generalizations from specific instances, while inductive reasoning focuses on specific cases.

• Deductive reasoning is based on personal experiences, while inductive reasoning relies on established facts.

Provide an example of an application of logic in a scientific context.

• The use of logic gates in computer hardware.

• The application of logic in artistic expression.

• The formulation of hypotheses in scientific research.

• The role of logic in historical analysis.

What is a counterexample in the context of logical reasoning?

• An example that illustrates a common belief.

• A general statement that supports a hypothesis.

• A specific case that contradicts a general statement or hypothesis.

• A case that confirms a theory or idea.

How can If-Then statements be used in hypothesis testing?

• If-Then statements cannot be applied to statistical analysis.

• If-Then statements are irrelevant to hypothesis formulation.

• If-Then statements help formulate hypotheses in hypothesis testing.

• If-Then statements are only used in programming languages.

What is the significance of Bayes' theorem in conditional probability?

• Bayes' theorem is significant in conditional probability as it enables the updating of probabilities based on new evidence.

• Bayes' theorem eliminates the need for prior probabilities.

• Bayes' theorem is used to calculate the mean of a dataset.

• Bayes' theorem is only applicable in discrete probability scenarios.

Describe a scenario where deductive reasoning is preferred over inductive reasoning.

• A legal argument where a lawyer deduces a citizen's rights based on established laws.

• A detective gathering clues to build a profile of a suspect.

• A teacher inferring a student's understanding from their test scores.

• A scientist forming a hypothesis based on experimental data.
