8. Unlike an experiment, the limitation of using a correlation is that is cannot establish .....

Correct Answer: Correct answer is: (B) Causation.

Exam Relevance: AP Psychology, IB Psychology, GRE Psychology

Difficulty: Moderate

Concept notes: Correlation measures the relationship between two variables but does not establish causation.

Common Mistakes: A common misunderstanding is that a strong correlation implies causation, which is not true.

Explanations: Correlation measures the strength and direction of the relationship between two variables, but it does not establish causation. Causation implies that changes in one variable directly cause changes in another variable. Correlation alone cannot determine whether one variable causes changes in another; it only indicates that the variables are related in some way. Therefore, the limitation of using a correlation is that it cannot establish causation.

Option Analysis:

Option A: Correlation can establish that a relationship exists between two variables.
Option B: Correlation cannot establish causation, which is the correct limitation.
Option C: Correlation can determine the strength of the relationship between two variables.
Option D: Correlation can determine the direction of the relationship between two variables.

9. All chickens that we have seen have been brown; so, all chickens are brown.

Correct Answer: Correct answer is: (B) Inductive.

Exam Relevance: GRE, GMAT, LSAT, Research Methods Exams

Difficulty: Moderate

Concept notes: The question involves distinguishing between deductive and inductive reasoning. Deductive reasoning starts with a general statement or hypothesis and examines the possibilities to reach a specific, logical conclusion. Inductive reasoning makes broad generalizations from specific observations.

Common Mistakes: A common mistake is confusing deductive reasoning, which starts with a general rule and applies it to a specific case, with inductive reasoning, which starts with specific observations and makes a general conclusion.

Explanations: The statement "All chickens that we have seen have been brown; so, all chickens are brown" is an example of inductive reasoning. It makes a general conclusion based on specific observations. Inductive reasoning does not guarantee the truth of the conclusion, but it provides a probable conclusion based on the evidence.

Option Analysis:

Option A: Deductive reasoning would involve starting with a general rule and applying it to a specific case, which is not the case here.
Option B: Inductive reasoning involves making a general conclusion based on specific observations, which matches the given statement.

10. The problem of ..... is that the future may not resemble the past.

Correct Answer: Correct answer is: (B) Induction.

Exam Relevance: GRE, GMAT, LSAT, Research Methods Exams

Difficulty: Moderate

Concept notes: Induction is a reasoning method that draws general conclusions from specific observations. The problem with induction is that it assumes the future will resemble the past, which may not always be true.

Common Mistakes: A common misunderstanding is that deduction, which involves deriving specific conclusions from general principles, is also subject to the same problem. However, deduction does not rely on the assumption that the future will resemble the past.

Explanations: Induction involves making generalizations based on observed patterns. The core issue with induction is that it assumes that what has been observed in the past will continue to hold true in the future. This assumption may not always be valid, as future events may differ from past observations. Deduction, on the other hand, does not rely on this assumption and instead derives specific conclusions from established general principles.

Option Analysis:

Option A: Deduction is a reasoning method that derives specific conclusions from general principles. It does not rely on the assumption that the future will resemble the past, so it is not subject to the same problem as induction.
Option B: Induction is a reasoning method that makes generalizations based on specific observations. The problem with induction is that it assumes the future will resemble the past, which may not always be true.
